Question

10) Two balls of masses 1.5kg and 2kg are about to hit a wall. If ball of mass 1.5kg is hitting the wall with a speed of 20m/s and the ball of mass 2kg with a speed of 15m/s, who will hit with greater kinetic energy? *


Answer fast​

Answer 1

Answer:

the first ball of 1.5 kg will hit the ball with greater kinetic energy

Step-by-step explanation:

for first ball

ke=1/2×1.5×20^2=300

for 2nd ball

ke= 1/2× 2× 15^2 = 225

so the first Ball will hit with greater kinetic energy by 70 j
