. A car is moving along a straight level road with
constant speed. Then
(a) the work done on the car is infinite
(b) the work done on the car is zero
(c) the work done on the car is a measure of
the gravitational potential energy
(d) the work done on the car cannot be found
2-2 rentesents the tinit of​

Answer 1

Answer:

Work done is zero as car is not accelerating so acceleration is zero. As work is the product of force and displacement . As force = ma , therefore Force is Zero. So work is Zero

Answer 2

work done is zero as a car is not accelerating so accelerating is zero as work is the product of force and displacement
