as it is given that curved marked the speed as v = 70 km/h
so we will first convert the speed into m/s
now we know that here friction force will provide centripetal force
As we know that centripetal force is given as

Explanation:
the work done to move the cart is equal to the product between the force applied and the distance traveled:
In this case, the force applied is F=209 N, while the distance covered is d=10 m, therefore the work done is
