A car engine produces a constant power of P = 246 hp at the wheel. The car an motor have a combined mass of m = 1880 kg.
1. Input an expression for the cars velocity V after a time t of supplying full power using the variables provided.
2. After t = 5 s what is the cars velocity in m/s?
3. A top fuel dragster of mass, m = 1000kg, can cover 400m in 7 secs. How much horsepower is the engine producing at the wheels?
