s = u.t - 12.(g+a).t2
s = 0.2t + 12.(g-a).(2t)2
02 = u2 - 2.(g+a).s
Now can you solve?
A block is given certain upward velocity along the incline of elevation α.The time of ascent to upper point was found to be half the time of descent to initial point.The co-efficient of friction between block and incline is:
