Question

a body is projected at an angle 30° with the horizontal with momentum P. at the highest point the magnitude of momentum is

Answer 1

Answer:

Explanation:

Initial k.E= p²/2m

Momentum at max height 'H' = P'

From law of conservation of energy

p²/2m = mgH + P'/2m

.

.

.

P'= p²-2m²gH

This is the answer ☝️
