Question

1. You are going to go help your family build a new patio cover. They asked you to bring along your hammer. You pull it out and notice that the head is loose on it. To tighten the head you can either hit the bottom of the handle hard against the ground or you can hit the hit of the hammer hard against the ground. Which method do you choose and why? 2. You have three identical boxes each with a mass of 5kg. You pull on the end rope with a force of 60N. What is the tension in the two other ropes? F=60N 3. Dargo (120kg) and Chiana (50kg) are both at the opposite ends of a rope that they are connected by. They are standing on a frozen lake. They are 15m apart when Dargo pulls on the rope. This gives Chiana an acceleration of 1.2m/s². a) what is Dargo's acceleration? b) If the force that Dargo applies is constant where will they meet? 4. You push a box up against a wall (see figure below). If the box has a mass of 1kg, and you push with a force of 12.5N at an angle of 30-degrees, will the box move up, down or stay stationary?
