Question

the ball has joules of potential energy at point B. At position A all of the energy changes to kinetic energy. The velocity of the ball at position A is meters/seconds. Assume theres no air resistance. use g=9.8m/s2

Answer 1

As I don’t see unit values we can do this with algebra gravitational potential energy is equal to mgh so you find that and then convert it to 1/2mv^2
