A crate of mass 11.5 kg is pulled up arough incline with an initialspeed of 1.50 m/s. The pulling forceis 100 N parallel to theincline, which makes an angle of16.0° with the horizontal.Thecoefficient of kinetic friction is 0.400, and the crate ispulled4.50 m.
(a) How much work is done by gravity?
Enter anumber.1J
(b) How much mechanical energy is lost due to friction?
Enter anumber.2 J
(c) How much work is done by the 100 Nforce?
Enter anumber.3 J
(d) What is the change in kinetic energy of the crate?
Enter anumber.4 J
(e) What is the speed of the crate after being pulled 4.50 m?
Enter anumber.5 m/s
