Vedclass · Answer

(C) The power generated by the engine must overcome the frictional force and provide the necessary acceleration to the car.First, calculate the frictional force $(f)$:$f = \mu m g = 0.5 	imes 1200 	imes 10 = 6000 \,N$Next, calculate the force required for acceleration $(F_a)$:$F_a = m a = 1200 	imes 2 = 2400 \,N$The total force $(F_T)$ produced by the engine is the sum of the frictional force and the accelerating force:$F_T = f + F_a = 6000 + 2400 = 8400 \,N$Finally, calculate the power $(P)$ using the formula $P = F_T v$, where $v = 20 \,m/s$:$P = 8400 	imes 20 = 168000 \,W$
