Question

When a ball is thrown vertically upwards. At the maximum height,

a)the velocity is zero and therefore there is no acceleration acting on the particle
b)the acceleration is present and therefore velocity is not zero.
c)the acceleration depends on the velocity as a = dv/dt
d)the acceleration is independent of the velocity.

Answer 1

Answer:

option d is correct.. even though at maximum height the velocity is zero , still there is acceleration bcoz even then earth is pulling it and exerting a force on it , and acceleration depends on force which comes from Newton's second law of motion..

Answer 2

Answer:

option d is correct ...
