The coefficients of friction between a block of mass 1.5 kg and a surface are ?s = 0.60 and ?k = 0.40. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is at rest and the surface is inclined at 15o? Use g = 9.79 m/s2.
Homework Answers
the normal force of the plane on the block is
Fn
= mgcos15
at rest, we use the
coefficient of static friction
Ff
= ?sFn
Ff = (0.60)1.5(9.79)cos15
Ff = 8.51 N

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...
