A 15.0 kg object is moved from the second floor of a house 3.00 m above the ground to the first floor 0.30 m above the ground. What is the change in gravitational potential energy?

An Atwood's machine was used by a student to determine the acceleration of two masses, m₁=73 grams and m2=70 grams. The pulley rotates freely, and the masses were released from rest and the vertical distance traveled by the masses is 80 cm. The student conducted 5 trials to measure the time it took the masses to travel the vertical distance of 80 cm. The measured time were 3.23 s, 3.08s, 3.43s, 3.29s and 3.67s. If the mass of the pulley is 95.74 grams determine: a. The experimental value of the acceleration b. The true value of the acceleration c. the percent difference between the experimental and true values of acceleration.
