Question

At what point of a projectile motion acceleration and velocity are perpendicular to each other
a} at the point of projectile
b} at point of drop
c} at topmost point
d} any where in between the point of projection topmost point

Answer 1

Answer:

at topmost point

in this case vertical component of velocity is 0 and there is only horizontal component.the acceleration is vertically downward, therefore acceleration and velocity at this point are perpendicular to each other

Answer 2

Any where in between the point of projection topmost point . Hope this answer helps you
