Question

A body of mass 0.05 kg travelling
with vertical wall
as shown in
fig. The body rebounds with
same speed making an angle of
30° with the wall. Find the
change in the momentum of
the 'body. (in kg-mis).​

Answer 1

Answer:

m=0.05kg

tita=30

let u[initial velocity]=a

let v[final velocity]=-a[as it rebounds]

J[Impulse]=m(v-u)

J=0.05(a-(-a))

J=0.05(2a)

J=0.10N

Answer 2

Answer:

you didn't mention the velocity value

Explanation:

Multiply 0.05 with v you'll get the momentum
