Solve the all parts of given problem:
Problem: An Atwood's machine has masses of 100 g and 110 g. The lighter mass is on the floor and the heavier mass is 75 cm above the floor.
Part A: How long will it take for the heavier mass to reach the floor?
Part B: What will be the speed of the two masses when the heavier mass hits the floor?
I need help to find the speed of the two masses when the heavier mass hits the floor.
