Question

A 6kg object speeds up from 5 m/s to 20 m/s. find p

Answer 1

Momentum = mass x speed

The object's momentum is 30 kg-m/s at the beginning, 120 kg-m/s at the end, and its change in momentum is 90 kg-m/s .

Answer 2

as we know tha momentum is product of mass and velocityi.e p=mv but here in this question velocity changes from 5m/s to 20 m/s so here formula becomes

p=(final velocity -initial velocity )mass

so (20-5)6=90kgm/s ANS
