Answer:
Step-by-step explanation:
Work done by the frictional force is 3.41x10^5 J
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
W = −340605 J
or Hence, the correct option is (a).
