James and John dive from an overhang into the lake below. James simply drops straight down from the edge. John takes a running start and jumps with an initial horizontal velocity of 25 m/s. Compare the time it takes each to reach the lake below. James reaches the surface of the lake first. John reaches the surface of the lake first. James and John will reach the surface of the lake at the same time. Cannot be determined without knowing...

i posted the firt question please answer the second pic
A 2.0-kg block is released from rest at point A. The track is frictionless except for the rough portion between points B and C. The block travels down the track, hits a spring of force constant 1000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. The mechanical energy of the system at point C is greater than the mechanical energy of the...
