Question

1) A 3kg mass is allowed to slide down a 5.0m ramp (? = 32°). If it takes 4.6s to go from rest to slide down the ramp, find the coefficient of friction (?). Hint: Find the acceleration first 2) An object is suspended with two ropes. If ? = 40° and T1 is 8N, find the mass. 3) 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 1st 5 seconds? 4) A 12.0 kg object is pulled to the right on a rough surface (? = 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?
