8. A force of 10 N acts upon a body of mass 2 kg.Calculate the acceleration.[Ans. 5 m/s2]

Answer»

Force = mass × acceleration

F=10N

m=2kg

then,

a=

m

F

=

10

=5m/s

2

(i) Now,

u=0

t=3sec

v=u+at=0+3×5=15m/s

(II)Initialmomentum=mu=2×0=0

Finalmomentum=mv=2×15=30kg−m/s

Change in momentum=Final momentum - Initial momentum

=30−0=30kg−m/s
