a 4 kg bowling ball videos rolling down a lane at bowling alley at 6 m/s when the ball strikes the pins is moving your 5.1 m/show much energy in the J is lost due to the friction?

19.98Joules

Explanation:

Energy possessed by the body is the kinetic energy

Kinetic Energy = 1/2mv²

m is the mass

v is the velocity

For the 4kg moving at 6m/s

kE = 1/2 * 4 * 6^2

KE = 1/2 * 4 * 36

KE = 72Joules

For the 4kg moving at 5.1m/s

kE = 1/2 * 4 * 5.1^2

KE = 1/2 * 4 *26.01

KE = 52.02Joules

Amount of Energy lost = 72 - 52.02

Amount of Energy lost = 19.98Joules

Hence the amount of Energy lost is 19.98Joules
