Astone is dropped from a bridge, and 2 seconds later a second stone is dropped. how far apart are the two
stones by the time the first one has reached a speed of 24.5 m/s?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

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:
