A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the table. a. How long is the ball in the air? b. With what horizontal velocity did the ball roll off the table? c. What is the vertical velocity of the ball just before it hits the floor? d. What is the horizontal velocity of the ball just before it hits the floor?

How is acceleration calculated? a. initial velocity - final velocity / timeb. initial velocity + final velocity / timec. final velocity - initial velocity / timed. final velocity / timele select the best answer from the choices provided0oood00save and exitnextmark this and return

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:
