Two weights, with masses 25 kg and 10 kg are connected through a lightweight rope over a pulley as shown in figure 2 below. Initially, the 10 kg mass rests on the floor while the 25 kg mass is held in position, two (2) meters above it.

a. Using the principle of conservation of energy, determine the speed of the 25 kg mass right before it strikes the floor.

b. Determine the acceleration of the 25 kg mass.

c. How long after letting go does it take the 25 kg mass to strike the floor?
