45. A particle is thrown vertically upward. When it reaches the highest point, it has A.A downward acceleration B.An upward acceleration C.A downward velocity D.A horizontal velocity
Option A Solution: When a particle is thrown vertically upwards in space, it will experience constant acceleration towards the ground (irrespective of the direction in which it is moving in), known as acceleration due to gravity. At the highest point, it has zero velocity but has downward acceleration equal to acceleration due to gravity.
