Question

Calculate the momentum of a body of mass 4 kg with kinetic energy is 25
49.4 kg m/s

Answer 1

Answer:

14.49

Explanation:

Relation BTW moments (p)

And kinetic energy (k. E)

Is given as

K. E =p^2/2m

25joul=p^2/2*4kg

25kgm^2/s^2=p^2/8kg

25*8 kg^2m^2/s^2=p^2

200kg^2m^2/s^2=p^2

Taking square root on both sides

14.49 kgm/s=p
