Q. A 63 kg trampoline artist jumps vertically upward from the top of a platform with a speed of 4.8 m/s. If the trampoline behaves like a spring of spring constant 6.2×10^4 N/m, how far does he depress it?
Q. Consider a rectangular block of metal of height A, width B, and length C. If a potential difference V is maintained between the two A B faces of the block, a current IAB is observed to flow. Find the current that flows if the same potential difference V is applied between the two B C faces of the block. Give your answer in terms of IAB. (Use the following variables as necessary: Iab for IAB, and A, B, and C.)
