You throw a tennis ball (mass 0.0570 kg) vertically upward. It leaves your hand moving at 15.0 m/s. Air resistance cannot be neglected, and the ball reaches a maximum height of 8.00 m. By how much does the total mechanical energy decrease from when the ball leaves your hand to when it reaches its maximum height? Express your answer with the appropriate units.

195 J

Explanation:

Given

mass of ball

ball leaves the hand with

maximum height reached by ball

Initial Mechanical energy when ball just leaves the hand

considering hand to be datum so h_1=0[/tex]

so Potential energy at ground is zero

Mechanical Energy at highest point

at highest Point velocity is zero

Decrease in Mechanical energy

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
