1. The problem statement, all variables and given/known data The brakes of a 1452 kg car bring it to a stop from a speed of 17.2 m/s in a distance of 100 m. If the car originally stops in 6.2 s (100 m), what power is developed by the brakes? 2. Relevant equations W = FF Δs W = ½ m· v^2 P = W/t P = F * v 3. The attempt at a solution W = 1/2 * m * v^2 W = 1/2 * 1452 kg * 6.2 s ^2 W = 214779.84 J P = W/t P = 214779.84 J/6.2 s P = 4501.2 W I know that this isn't correct because it is a multiple choice study guide. The options are the following: a. 230 kW b. 34.7 kW c. 23.4 kW d. 2.15 kW It is the only problem I can't solve, and I'd like to know how to! Thank you.
