Question
A 5.0 kg crate is pulled up a rough 20° incline by a 145 N force parallel to the incline
A 5.0 kg crate is pulled up a rough 20° incline by a 145 N force parallel to the incline. The initial speed of the crate is 2.5 m/s, the coefficient of kineticfriction is 0.40 and the crate is pulled a distance of 5.00 m. Determine how much work is done by
(a) the gravitational force, and
(b) the 145 N force?
(c) What is the change in kinetic energy of the crate?
(d) What is the speed of the crate after it is pulled 5.00 m?
