Question

29. A 100 g ball having speed 10 m/s collides with
a wall and rebounds with the same speed and the
contact period between the ball and wall is
0.1 second, then the force experienced by the wall
is​

Answer 1

Answer:

F = mass × acceleration

Given

mass = 100g

u = 10m/s

t = 0.1

and acceleration = (v-u)/t

now

given that |u| = |v| = 10m/s

but direction is opposite as it rebounds

then

u =10 m/s

v =-10 m/s

then acceleration

now as

a = -200m/s^2

then force

Or force experience by wall

= 20 Newton

In magnitude
