Dave throws a tennis ball straight up into the air he throws the ball with mass of 0.07 kg A speed of 28 m/s and there is no air resistance how high does the ball A speed of 28 m/s and there’s no air resistance how high does the ball go
First notice some physics; the mass of the ball (projectiles) is not germane. A 2 ton elephant launched at U = 28 m/s will go just as high, which is H = U^2/2g = 28^2/(2*9.8) = 40 meters.
