A particle is thrown up vertically with a velocity of 15m/s.what will be its velocity at the highest point of the journey ? how hgh would it rise and at

what time would it take to reach the highest point.(take g=10m/s)


Velocity at the highest point = 0m/s
height it rises = v∧2/2g = 15∧2/2*10
                                   = 225/20
                                   = 11.25m
time = v/a = 15/10
                = 1.5 sec
