Problem
A small block is projected upward along a rough fixed incline that is at 25∘ to the horizontal with an initial speed of 6.0m s−1. The coefficient of kinetic friction between the block and the surface is 0.15. Neglect air resistance.
(i) Calculate the retardation (magnitude of acceleration) of the block as it moves up the plane.
(ii) Determine the distance it travels up the plane before coming to instantaneous rest.
(iii) Find the time interval between the instant of projection and the instant it comes to rest.
