1. The problem statement, all variables and given/known data Pete serves a tennis ball of mass 54 grams at a speed of 53.6 meters per second. The ball is in contact with Pete's racket through a distance of 49.7 centimeters. What force does Pete apply to the ball? 54 grams = 0.054 kg Speed = 53.6 m/s 49.7 cm = 0.0497 m 2. Relevant equations Force = mass x acceleration Vfinal = at + vi 3. The attempt at a solution I am VERY lost, considering the fact that our teacher told us to try and figure it any way we could. I tried this. 0.0497 m = 0.5(53.6 m/s) * t2 t = 0.0420183500 s Then I thought of the statement It takes 0.0420183500 seconds to travel 0.0497 m when traveling at 53.6 m/s Then I tried Vfinal = a*t + Vinitial 56.3 m/s = a * 0.0420183500 s a = 1339.890784 m/s2 Force = 0.054 kg * 1339.890784 m/s/s Force = 72.4 N Can anyone help me out with this please?
