Answer» HYY Dude 30J Explanation: At maximum HEIGHT there is only horizontal component of velocity because there is no acceleration in x direction if we take this motion in x-y plane ,so as the ball has only horizontal velocity which is 20m/s then the K.E of the ball is=1/2×0.15×(20)²=30J May this helps you |
