Question

After the 2,500-m swim, Charlie [mass mCh = 42 kg] wants to impress Colby [mC = 34 kg] and jumps off the 10-m platform. Charlie jumps upwards and reaches the maximum height of 2.5-m above the platform before turning around and falling towards the water. We only consider the motion along the vertical. a) Find the velocity [vector] of Charlie as he jumps off the spring board. b) Find the velocity [vector!] of Charlie as he hits the water surface. c) How long is Charlie airborne? 6 d) Charlie then plunges into the water and reaches the maximum depth 4.6-m [15 ft] below the surface. What is the (average) magnitude of the deceleration of Charlie while he is submerged in water. e) What is the (average) force that the water exerts on Charlie as he is submerged in the water?
