You are driving a car and are at a stop light. When the light turns green, you
step on the gas and accelerate at 6.Omi/hr2. Your final speed is 60 miles per
hour (mi/hr or mph). How much time did it take you to get to your final speed?

Answers

Answer:

t= 10 hr

Explanation:

v(final)=v(initial)+at

60 mi/hr= 0 mi/hr+ (6 mi/hr2)t

(60 mi/hr)/(6 mi/hr2)=t

t= 10 hr

A car is moving at 18 m/s when it accelerates at 8 m/s2 for 2 sec. What is his new velocity ?

Answers

Vf= at + Vi
Since at = 8m/s2 * 2 = 16m/s2
Vi=18m/s
=>Vf = 16m/s2 + 18m/s = 34m/s
So, the new velocity is 34m/s

The force of something stronger than the muscles causes it to increase its tension as it
gets longer.

False
True

Answers

The answer is trueI just Finnishd

The force of something stronger than the muscles causes it to increase its tension as it gets longer is true.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Frictional force allows the ball to stay in the hand while muscular force is employed to stop the motion of the ball during catching. Throughout this activity, the Earth's gravitational pull on the ball is constant.

The force of something stronger than the muscles causes it to increase its tension as it gets longer is true.

what is the average velocity of a car that travels 30 kilometers due west in 0.50 hour

Answers

Divide the distance traveled (0.30 km) by the travel time (0.50 hrs) and get the speed in km/hr. The direction is due west. 60 km/hr west

The average velocity of a car that travels 30 kilometers due west in 0.50 hour - 60 km/hour west.

Average velocity is the displacement of an object with the time change. To find the average speed of an object we divide the distance travelled by the time elapsed.

Velocity is a vector quantity and average velocity can be found by dividing displacement by time.Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs

Average velocity = ∆x/∆t

Then,

average velocity = 30/0.5

= 300/5

= 60

Thus, the correct answer would be - 60 km/hour west.

Alan travels 100 km in 5hrs. Find his average speed in km/h​

Answers

25 km/h hope this helps

Answer:

The answer is 20 km/hr

Explanation:

The average speed of an object given the time and distance covered can be found by using the formula

[tex]a = \frac{d}{t} \\ [/tex]

where

d is the distance

t is the time

From the question

d = 100 km

t = 5 hrs

We have

[tex]a = \frac{100}{5} \\ [/tex]

We have the final answer as

20 km/hr

Answers

Answer:

C 31500

Explanation:

1/2mv*2=KE

k.e= 350× (30)*2

=350×900

k.e= 31500

It is d because you have to do 300 - 50 then take of the zero for 30.After that do 3x300 and you get 900
