Answer 1

Answer:

1)p=20kgm/s

v=2m/s

2)p=30kgm/s

v=3m/s

3)p=40kgm/s

v=4m/s

4)p=50kgm/s

v=5m)s

Answer 2

3.A particle of 10 kg is moving in a constant acceleration 2m/s 2  starting from rest.

What is its momentum and velocity per the table given below

S.No time Momentum Velocity

1 1sec

2 1.5 sec

3 2 sec

4 2.5 sec

Solution

Velocity can find using

v=u+at

For u=0

v=at

Momentum

P=mv

S.No time Momentum Velocity

1 1sec 20 Kg m/s 2 m/

2 1.5 sec 30 kg m/s 3 m/s

3 2 sec 40 kg m/s 4 m/s

4 2.5 sec 50 kg m/s 5 m/s
