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.

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

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 350 kg motorcycle moves with a velocity of 30 m/s. What is its kinetic energy?
10500 Joules
c. 31500 Joules
b. 157500 Joules
d. 900 Joules

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
