- 1. A visibly distraught Granny has emerged from her car (it seems everyone has been ignoring her and talking about planets), and is trying to get back on the road. She puts a shoulder against the rear bumper of her car (m 1600 kg) and applies a constant force of 20.0 N for a full 20.0 seconds. The car does not budge. How much work has Granny done? -A 12.0 kg box is given an initial push that starts it sliding across the floor. It eventually comes to a stop. If the box has an initial velocity of 3.5 m/s, how much work is done by friction to cause it to come to a stop? (Yes, you are correct, you do not know the coefficient of friction.)It takes 87 J of work to stretch an ideal spring from 1.4 m to 2.9 m from equilibrium. What is the value of the spring constant (force constant) of this spring?
- A7.1 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force F between t = 0 and t = 1.2 s? 0.5 s 1.0 s 1.5 s 2.0 s 0.2 (0.4 0.6 0.8 х (m) Number UnitsA 72.0 kgkg painter climbs a ladder that is 2.75 mm long leans against a vertical wall.
