A van travels on a rough level road with an initial speed vo. The road has a coefficient of kinetic friction Hk. At the instant when the brakes lock, the tires slide than roll. 1. List down the forces that do work on the car. 2. Use the work-kinetic energy theorem to determine the minimum stopping distance of the car in terms of its initial velocity vo, the acceleration due to gravity g and the coefficient uk. 3. Using one of the kinematic equations, determine the time it takes for the car to stop in terms of the initial velocity vo. 4. Use your previous result to determine the power it takes for the car to stop completely.

A car engine produces a constant power of P = 341 hp. The car and motor have a combined mass of m = 1830 kg. 1.) The car starts from rest, after t=5 seconds, what is the cars speed, you may assume no energy is required to spin the tires. 2.) Assume a dragster of mass m=1000kg can accelerate to cover 450 m and accelerate in 7.2 s from a dead stop, how much horsepower is the engine producing, assuming acceleration is constant?

speed will be v=3.76ms A water skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 72kg water skier has an initial speed of 6.0m/s. 5.0 seconds later, the speed increases to 11.2m/s. What is the net work done on the water skier? If we assume the efficiency in converting kinetic energy from the boat to the water skier is only 20%, what is the power of the boat? What is the amount of work done by the resistive force during the 5-second period? Answer: W =m(v -v)- 3219.84J × 3.2×10°J net 3219.84J The power of the boat will be P=- = 3.2x10 W 0.2x5s =-3.2×10'W×0.8×5s =-1.3×10ʻJ resistive W. 3

1480 kg car accelerates uniformly from a position of rest to a speed of 95 km/h in 6.0 s. a) Calculate the car's acceleration. b) How far did the car travel during this acceleration? b) How much work was done by the car during this 6.0 s?
Which of the following statements are true? Select all correct. Question 3 options: If an object speeds up, then the total work done on the object was positive. If an object moves at a constant speed, then the work done by each individual force is zero A force must be parallel to the displacement to do any work. If a force is perpendicular to displacement, it does zero work. If a force has a component in the opposite direction of the displacement, it does positive work. If an object doesn't move, then the work done by every individual force must be zero.
