Question

K.E of a body of mass 2kg and momentum 2 Ns is?​

Answer 1

Explanation:

momentum=mass×velocity

2=2×velocity

velocity=1 m

kinetic energy=1/2 mv^2

=1/2×2×1^2

=1m/s

Answer 2

Momentum = Mass × velocity

velocity = momentum ÷ mass

v = 2÷2 = 1 m/s

K.E. = 1/2 × m × v^2

= 1/2 × 2 × 1^2

= 1 J
