A 20 kg lawn mower has a handle angle of 25° and is on a μ=0.09 horizontal surface. If a push force of 26 N is applied to the handle, and the mower is displaced by 10.0 meters, find 

a) work done by the push  b) work done by friction  c) the time for the motion

 

2. The following force-distance graph shows the work done on a 10kg mass, which starts at rest on a horizontal fricitonless surface. Force (N) 40N Find, for d= 3.7 m the following: a) the work done: Check b) the final speed of the object: O distance(m) m/s
