Given : Two bodies of masses 2 kg and 5 kg respectively are moving at same velocity.
To find : What is the ratio of their kinetic energy.
Using formula :
★ KE = 1/2 mv².
Calculations :
→ KE = 1/2 mv²
→ KE 1/2 = 1/2 m1 v1/1/2 m2 v2
→ KE 1/2 = m1/m2
→ KE 1/2 = 2/5
→ KE = KE1 : KE2
→ KE 1 : KE 2 = 2 : 5
Therefore, the ratio of their kinetic energy will be 2:5.
