calculate the kinetic energy of a mass 100gms and momentum 20kg m/s
Asked by bharadwajlucky26 | 12 Sep, 2018, 04:54: PM
answered-by-expert Expert Answer
mass = 100gms = 0.100
momentum = 20 kg m/s
momentum (p) = mass (m) x velocity (v)
20 = 0.10 kg x v
v = 20 / 0.10 = 200 m/s
kinetic energy (KE)  = 1/2 mv2 
KE = 2000 J
