Answer:
a) wet marble , dry marble, newspaper, and towel
Answer:
Power, P = 112500 watts
Explanation:
It is given that,
Mass of the car, m = 1500 kg
Initial velocity of the car, u = 0
Final velocity of the car, v = 30 m/s
Time taken, t = 6 s
The minimum average power delivered by the engine is given by :
P = W/t
Where
W = work done
t = time taken
Work done = change in kinetic energy
So,
P = 112500 watts
So, the minimum average power delivered by the engine is 112500 watts. Hence, this is the required solution.
