Question

In the figure the second block slides horizontally without friction while the first block falls. Use the Conservation of Energy to find the speed of the blocks after they have moved 2 meters, starting from rest. The falling block has mass 3 kg, the sliding block has mass 5 kg, and the pulley is ideal.

Explanation / Answer

Block 1: x: 0 y: E1 = m1.g.h Block 2: x: E2 = 1/2.m2.v^2 y: 0 Velocity: E1 = E2 1/2.m2.v^2 = m1.g.h v = sqrt(2.m1.g.h/m2) v = sqrt(2*9.8*3*2/5) v = 4.85 m/sec remember to rate my work ... :)
