a) Describe the motion of the object. b) What time frame is the object accelerating the most? c) At what time frame is the object not accelerating? d) What was the displacement for the 1# 5 seconds? 4) A 12.0 kg object is pulled to the right on a rough surface (u = 0.6) with a constant force T. It moves to the right at a constant speed of 3.0 m/s. It then moves onto a frictionless surface. T is applied during the entire scenario. a) Find the value of T. b) Find the acceleration of the block when on the rough surface and on the frictionless surface. c) How far does the object need to slide on the frictionless surface to reach 8.0 m/s? 5) A 75 kg man standing on a scale in an elevator notes that as the elevator rises, the scale reads 825 N. what is the acceleration of the elevator? howt a block of mass m resting on a 20 slope
