To keep a lorry moving at a constant speed v, requires power p, from the engine. The force provided by the engine is
A
\(\frac{1}{2}\)v
B
pv
C
\(\frac{p}{v}\)
D
pv2
E
\(\frac{p}{v^2}\)
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Power(p) = Force(F) x velocity(v)
F = \(\frac{\text{power}}{\text{velocity}}\)
