Answer:

Step-by-step explanation:
Given that,
Force exerted on an antique car, F = 270 N
Time, t = 0.275 s
Distance, d = 0.3 m
To find:
The angular momentum given to the engine.
Solution,
We know that the relation between the angular momentum and the torque is given by :

Since,







So, the angular momentum given to the engine is
.
