how can the velocity of a vertically upward projected body is equal to zero at the maximum height
it cannot be because only when the particle comes back the velocity becomes 0

Answer:
ANSWER
time taken by the body from going to top after seen from height H is equal to time taken by the body from top to height H.
so time will be

(t

−t

.
total time to reach from ground to top is t

+t

. time of flight is known we can take this in reverse direction initially at top with zero velocity and acceleration g, then find displacement after time of flight

(t

so h=ut+

so option D is best possible answer

Answer:
When a body is thrown vertically upwards, at the highest point only velocity is zero because the acceleration due to gravitational force is acting downward continuously and that is the reason for velocity being zero at the highest point, hence velocity is zero because of the acceleration.
