The work done on the ball by GRAVITY = mgh = .981 J
It's final KE = .981J
It's find velocity = sqrt(2*KE/m)= 6.26 m/s
Sweet N.
asked 03/22/21A 50-g ball is dropped from a height of 2.0m. (a.) What is the work done on it by its weight? (b.) What is its final kinetic energy? (c.) What is its final speed? *
PLEASE HELP!!!
