At 9.20m, all of the kinetic energy will be potential energy, so just calculate the potential energy at the 9.20m mark.
P.E.=mgh=(0.500kg)(9.8m/s^2)(9.20m)=K.E.@ 9.20m
Determine the kinetic energy required to throw a 500g ball vertically to a height of 9.20m?

If a swimmer completes the length of a 50 m Olympic Pool in 25.0 s then it means that the swimmer:
a) maintained a constant speed of 2.0 ms-1. -1
b) probably swam with a speed greater than 2.0 ms during the first 25 m.
c) had an average speed of 2.0 ms-1. -1
d) maintained a constant velocity of 2.0 ms for all of the swim.
