Question

An object of mass 100 kg is accelerated uniformly from a velocity of 5m/s in 6 s calculate the initial and final momentum of the object. also, find the magnitude of force, exerted on the object

Answer 1

Explanation:

p =mv

=100*5

=500 kg. m/s

now,

v=5m/s. u= 0 t= 6s

a= v-u/t

=5-0/6

=5/6 m/s square.

F= ma

=100*5/6

=500/6

=250/3 kgm/squ.
