Question

a mass of 6 kg has kinetic energy of mass 300 joule calculate the momentum of their object​

Answer 1

Answer:

momentum = 60

pls mark me brainliest

Answer 2

Answer:

K.E=p2/2m

p = 3000 kg m/sec and m = 60 kg

This is the relation obtained from two formulae,

 p=m×v and K.E=21×m×v2

Hence K.E=2mp2=2×6030002J

K.E=75×103J.
