Question

A block is projected up along a rough incline with
a velocity of u = 10 m/s. After 4 s the block was
at point B at a distance of 5 m from the starting
point A and was travelling down at a velocity of
v = 4 m/s.

(a) Find time after projection at which the block
came to rest.
(b) Find the coefficient of friction between the
block and the incline.
Take g = 10 m/s2
Pls give the detailed explanation
