Homework Statement
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.
Homework Equations
P=W/T
Sliding force of the slope = 1100g(sinTheta)
A= 16.67/6.5 --> 2.56m/s^2
SF=MA
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 don't know how to incorperate that fact that the car is climbing at 20kph.
