Question

1. A particle is projected vertically upward with a velocity of 10 ms. The velocity of the particle when it again reaches the points of projection after 2 seconds is (neglecting ai

resistance).

Answer 1

Answer:

At the highest point, the speed of the particle will be zero. Here speed is in upward direction and acceleration is in the downward direction. Hence, the sign of acceleration should be negative. At highest point, the velocity of the particle will (a) be zero.
