The engine of a 2000 kg mercedes going up pike’s peak delivers energy to its drive wheel at the rate 100 kw . neglecting air resistance, what is the largest speed the car can sustain on the steep pike’s peak mountain highway, where the road is 30° to the horizontal? the acceleration due to gravity is 10 m/s².
1. 10 m/s
2. 20 m/s
3. 100 m/s
4. 40 m/s
5. 0 m/s
