A particle passes through points X and Y; which are 100 m apart; It takes 5 sec to cover this distance with uniform acceleration. At point Y the particle’s velocity is 25m/s; What is the initial velocity at point X?
15 m/s
24 m/s
20 m/s
21 m/s
Let us use the equation of motion
Let us put the values
therefore; the initial velocity() is given by
