Liz and Jacqueline each hit a golf ball off the top of an ocean cliff. Liz's ball has a horizontal velocity of 20 m/s and a vertical velocity of 1 m/s. Jacqueline's ball has a horizontal velocity of 20 m/s and a vertical velocity of 2 m/s. Which of the following statements is true?​

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:
