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

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
