Hello !
Momentum = mass x velocity
mass = 2 kg
momentum = 2 N/s
Velocity = momentum/mass
= 2/2
= 1 m/s
Kinetic energy = 1/2 mv²
= 1/2 × 2 × 1²
= 1 Joule
Kinetic energy of the body = 1 J
Momentum = mass x velocity

Answer:
1 J
Explanation:
momentum=2 ms
mass=2kg
momentum=m×v
therefore v=momentum/m
=2/2 = 1m/s
k.E= 1/2 mv²
= 1/2 × 2×1²
= 1J
