Question# 1:- Suppose a block with a mass of 3.25 kg is resting on a ramp. If the coe!cient of static friction between the block and ramp is 0.250, what maximum angle can the ramp make with the horizontal before the block starts to slip down?
Question# 2:- The hockey puck, struck by a hockey stick, is given an initial speed of 20.0 m/s on a frozen pond. The puck remains on the ice and slides 1.30?102 m, slowing down steadily until it comes to rest. Determine the coe!cient of kinetic friction between the puck and the ice.
Question# 3:- An experimental rocket plane lands on skids on a dry lake bed. If it's traveling at 80.0 m/s when it touches down, how far does it slide before coming to rest? Assume the coe!cient of kinetic friction between the skids and the lake bed is 0.600.
Question# 4:- An object of mass 2.0 kg starts from rest and slides down an inclined plane 80 cm long in 0.50 s. What net force is acting on the object along the incline?
Question# 5:- An object with mass m1 = 25.00 kg rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 10.0 kg. Find the acceleration of each object and the tension in the cable.
Question# 6:- The coe!cient of static friction between the 3.00 kg crate and the 35.0! incline of Figure is 0.300. What minimum force F must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline?
Question# 7:- Find the acceleration reached by each of the two objects shown in Figure if the coefficient of kinetic friction between the 7.00 kg object and the plane is 0.250.
