1. The problem statement, all variables and given/known data A 1100kg car can accelerate from 0-60kph in 6.5 seconds. With constant engine power, what is the steepest hill the car could climb at 20 kph. 2. Relevant equations P=W/T Sliding force of the slope = 1100g(sinTheta) A= 16.67/6.5 --> 2.56m/s^2 SF=MA 3. The attempt at a solution I found the sum of the forces (1100 * 2.56) = 2816 and set the equation up as ... 2816=1100g(sinTheta) though I know this is wrong because the answer is 23. I dont know how to incorperate that fact that the car is climbing at 20kph.
