Report

When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). The racquet exerts a force of 540 $\mathrm{N}$ on the ball for 5.00 $\mathrm{ms}$ , giving it a final velocity of 45.0 $\mathrm{m} / \mathrm{s} .$ Using these data, find the mass of the ball.

$m = 0.06 \mathrm { kg } = 60.0 \mathrm { g }$

Okay. Okay. The the player applies off worse off. I'm 40 Newton. So Force F is equal to 540 Nugent. How long For five minutes? Seconds of time. T is equality. Five minutes seconds. So let's convert this into a scientist. So that is five into due to the power minus three seconds. Right now. Uh, Miss University off the wall. Get your highest big zero. And the final diversity is 45 meters per second after the clear crystal ball. So we need to come with the mass of the ball from Newton's second off motion. That is a physical to m A. So we can figure out the formula for M from this equation. Every single force applied upon acceleration right now again acceleration. Is it going to the chains in diversity pouring in time? Right. Easy call to be minus your teeth. So this gives me and is he going to? That's a pawn B minus you and bitey City goes up here. Now we have everything requires at least 540 tee time is five seconds. 5493 B minus Siri's 45. So calculated this you get Mr B zero point Jiro six Gezi on this equal stew 60 grams. Okay, so this answers the human question
