4. For this series of 4 questions, two blocks, A and B, are connected using the cable and pulley system as shown. (The cable and pulley system is friction-less and weight- less.) The coefficient of kinetic friction between block A and the inclined plane is k = 0. 2. Initially the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) If at an instant block A moves down the plane at a velocity of 7.8 ft/s, determine the velocity of block B at this instant. Your answer must include 1 place after the decimal point and the proper unit. The velocity is positive if block B moves upwards. A B C D

Transcribed Image Text:4. For this series of 4 questions, two blocks, A and B, are connected using the cable
and pulley system as shown. (The cable and pulley system is friction-less and weight-
less.) The coefficient of kinetic friction between block A and the inclined plane is
k = 0. 2. Initially the blocks are moving but eventually come to stop. You will be
asked to solve for different things. Please pay attention: the numbers may
change from problem to problem since they are randomized.
2) If at an instant block A moves down the plane at a velocity of 7.8 ft/s, determine
the velocity of block B at this instant. Your answer must include 1 place after the
decimal point and the proper unit. The velocity is positive if block B moves upwards.
