Question

A body of mass 3 kg moving with velocity 10 ml
s hits a wall at an angle of 60' and returns at the
same angle. The impact time was 0.2 s. Calculate
the force exerted on the wall.​

Answer 1

Answer:

F=150N

Explanation:

body of mass =3kg

velocity = 10m/s

time = 0.2s

for acceleration :

v=u+at

10=0+a×0.2

10=0.2a

a= 50

Force = Mass × acceleration

= 3 × 50

=150
