A woman pushes her 150kg motorcycle up a slope of 5 degrees with a constant speed of 2 m/s. She achieves this by exerting a force on the bike of 450N parallel to the slope. What is the magnitude of the frictional force acting on the bike?
The Attempt at a Solution
a= (150 x 9.8) x sin5
F= 150 x 128
but the answer is ment to be 322 N, im not realy sure where I am going wrong, any help would be greatly appriciated
