Question

Momentum at the highest point = 0.5 x 0 = 0 kg.m/s
Lakhmir Singh Physics Class 9

Answer 1

yes, of course momentum at highest point = 0 Kgm/s.

explanation : when a particle of mass m kg is thrown with a velocity u m/s, after reaching maximum height, particle becomes rest. i.e., velocity at maximum height , v = 0 m/s

but we know,

momentum = mass of body × velocity of that body

so, momentum at maximum height = mass of particle × velocity of particle at maximum height.

= m kg × 0 = 0 Kgm/s

[ note : but change in momentum is not equal to zero. because initial momentum of particle = mu ≠ 0 that's why, change in momentum = final momentum - initial momentum ≠ 0 ]
