What is the magnitude of the force acting on the puck?
Two blocks are connected via a massless frictionless pully system. The hanging block is 3 kg. The other block is on a ramp of 25◦ and has a mass m. The coefficients of friction between the block on the ramp and the ramp are: µs = .8 and µk = .5. a. What is the minimum mass m that will not slip? b. If the minimum mass is nudged, it will start being pulled up the incline. What will the acceleration be when that happens?
A block and a ball are connected by a string as shown in the figure. The block sits on a level, rough surface. The coefficient of static friction between the block and the surface is μ = 0.841.

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?
