A 2kg block is projected up a rough plane that is inclined at 20∘ to the horizontal with an initial speed of 5ms−1. The coefficient of kinetic friction between the block and the plane is 0.25. Take g=10ms−2. How far up the plane will the block move before coming momentarily to rest?
a) 5.3m
b) 1.1m
c) 2.2m
d) 3.7m
