Two blocks are connected by a light string that passes over a frictionless pulley as in the figure below. The system is released from rest while m2 is on the floor and m1 is a distance h above the floor. Two objects are connected by a taught string passing over a pulley. An object labeled m2 rests on a table, and an object labeled m1 dangles a distance h above the table. (a) Assuming m1 > m2, find an expression for the speed of m1 just as it reaches the floor. (Use any variable or symbol stated above along with the following as necessary: g.) vf = (b) Taking m1 = 6.3 kg, m2 = 4.3 kg, and h = 3.5 m, evaluate your answer to part (a). m/s (c) Find the speed of each block when m1 has fallen a distance of 1.7 m. m/s
