Question

when a force acts on a body of mass 10gm initially at rest, it acquries a velocity of 15m/sec. find acceleration and the magnitude of the force.​

Answer 1

mass=10g

      =10(raise to the power -2 kg)

initial velocity=0

final velocity=15m/s

time taken=5s

Explanation:

a=v-u/t

a=15-0/5

a=3ms(raise to the power -2)

now,

force=Ma

F=3X10(raise to the power -2)

now,

final momentum

p=Mv

P= 15x10(raise to the power -2) kg.ms(raise to the power-1)
