1. The problem statement, all variables and given/known data A 240gram toy car is driven by an electric motor that has a constant power output. The car can climb a 24° incline at 16m/s and can travel on a horizontal table at 39m/s. The frictional force retarding the motion is kv, where k is a constant and v is its speed. How steep an incline can it climb with a speed of 28m/s? 3. The attempt at a solution I've tried solving this for 2 days now and but not succeeded. It seems quite simple but it is the kv part that I don't know how to use. Please could someone explain how to solve it? Help is very much appreciated! Thank you!
