You have landed on an unknown planet, Newtonia, and want to know what objects will weigh there. You find that when a certain tool is pushed on a frictionless horizontal surface by a 12.9 N force, it moves 16.8 m in the first 2.20 s, starting from rest. You next observe that if you release this tool from rest at 10.0 m above the ground, it takes 2.78 s to reach the ground. 1. What does the tool weigh on Newtonia? 2. What would it weigh on Earth?

Two blocks, M1 and M2 are connected by a massless string that passes over a mass-less pulley as shown in the figure. M2 which has a mass of 19.0 kg, rests on a long ramp of angle θ=25.0o. Friction can be ignored in this problem. If the actual mass of M1 is 5.00 kg and the system is allowed to move, what is the acceleration ?a of the two blocks? A positive acceleration corresponds to M2 moving up the incline.What distance d does block M2 move in 2.00 s?
