Two cars with equal mass race on the same circular race track. Car A travels faster than car B How does the centripetal force exerted on each car compare?

True or false graphs must include scales that increase by the same amount

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

Which best describes the difference between internal and thermal energy?
