1. During an accident investigation, a detective measures the skid marks that a car
left to determine how fast it was initially moving before stopping when it hit a
light pole. The detective measures the distance to be 40 meters. The detective
receives the car's braking acceleration to be 4.57m/s2 from the manufacturer's
manual. Help the detective by solving how fast the car was initially going before
he hit the light pole? Someone please help I’ll give you a brainlest

Answer:

1 m/s  

Explanation:

2 to 3 second interval would be zero.

3 to 4 is 2 m/s

so average is 1 m/s

Answer:

The newton’s second law is F=ma

The Gravitational force is [tex]F=\dfrac{Gm_{1}m_{2}}{r^2}[/tex]

Explanation:

Given that,

The equivalent formulas for velocity, acceleration, and force using the relationships covered for UCM, Newton’s Laws, and Gravitation.

We know that,

Velocity :

The velocity is equal to the rate of position of the object.

[tex]v=\dfrac{dx}{dt}[/tex]....(I)

Acceleration :

The acceleration is equal to the rate of velocity of the object.

[tex]a=\dfrac{dv}{dt}[/tex]....(II)

Newton’s second Laws

The force is equal to the change in momentum.

In mathematically,

[tex]F=\dfrac{d(p)}{dt}[/tex]

Put the value of p

[tex]F=\dfrac{d(mv)}{dt}[/tex]

[tex]F=m\dfrac{dv}{dt}[/tex]

Put the value from equation (II)

[tex]F=ma[/tex]

This is newton’s second laws.

Gravitational force :

The force is equal to the product of mass of objects and divided by square of distance.

In mathematically,

[tex]F=\dfrac{Gm_{1}m_{2}}{r^2}[/tex]

Where, m₁₂ = mass of first object

m= mass of second object

r = distance between both objects

Hence, The newton’s second law is F=ma

The Gravitational force is [tex]F=\dfrac{Gm_{1}m_{2}}{r^2}[/tex]

Explanation:

The voltage of the circuit will be 0.75 V.The potential difference between the circuit is known as the voltage.

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically as,

The Equation of Ohm's Law

[tex]\rm V=IR \\\\ V= 0.05 \times 15.2 \\\\\ \rm V=0.75 \ V[/tex]

The voltage of the circuit will be 0.75 V.

Hence option D is correct.

Answer:

The velocity of Alice (25 m/s) will be greater than that of Tom (0), when  they reach the lake below.

Explanation:

Given;

initial horizontal velocity of Tom is zero since he dropped straight down from the edge.

initial horizontal velocity of Alice is 25 m/s.

Their respective horizontal velocity when they jumped is the same as when they reach the lake below.

If we compare their velocities when they reach the lake, one will be greater than the other, if we neglect air resistance.

Thus, the velocity of Alice (25 m/s) will be greater than that of Tom (0), when  they reach the lake below.

3.0m/s so it’s number 5

Explanation:

The magnitude of the player's average velocity during the drill is 0 m/s.

The given parameters;

Average velocity is change in displacement per change in time of motion.

[tex]\Delta \bar v = \frac{\Delta x}{\Delta t}[/tex]

where;

The change displacement is zero, since the player moved forward and back to the exact initial position.

[tex]\Delta \bar v = \frac{3(30) - 3(30) }{60} = 0[/tex]

Thus, the magnitude of the player's average velocity during the drill is 0 m/s.

Answer:

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

Explanation:

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

Explanation:

Answer:

See attached answer.

Explanation:

To solve this we must be knowing each and every concept related to displacement and its calculations. Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.

The distance along a straight line connecting an object's original and final positions is its displacement [x].

Displacements are not always a good thing. It may also be 0 or negative. A negative displacement indicates that the item has moved away from the origin and toward the right if a positive direction is situated to the right of both the origin.

If the body's velocity at a given moment in time is 'v' m/s, then displacement may be expressed mathematically as-

v = dx /dt

dx = vdt

Integrating on both sides, we get

∫dx = ∫vdt

∫dx  [x = 0 to x = x] = ∫vdt  [ t = 0 to t = 16 s]

x = v [16 - 0]

x = 16v

Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.

C (Celsius) is the correct symbol for the metric (SI) unit of temperature. The correct option is D.

The Celsius scale is widely used for measuring temperature in the metric system.

In certain scientific and engineering fields, such as thermodynamics, the Kelvin scale (symbol: K) is also used as an absolute temperature scale but the SI unit of temperature is Celsius.

Thus, the correct option is D.
