The small slider of mass m = 0.76 kg is released from rest while in position a and then slides along the vertical-plane track. the track is smooth from a to d and rough (coefficient of kinetic friction μk = 0.24) from point d on. determine (a) the normal force nb exerted by the track on the slider just after it passes point b, (b) the normal force nc exerted by the track on the slider as it passes the bottom point c, and (c) the distance s traveled along the incline past point d before the slider stops. the distance r = 1.32 m.

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
