If a car used 260,000 w of power to complete a race in 15 s, how much work did the car do?

the answer is J. 3,900,000 got it right on the test

P = power used by the car = 260,000 Watt

t = time taken by the car to complete the race = 15 sec

W = work done by the car to complete the race = ?

Work done by the car is given as

W = P t

inserting the values given above

W = (260,000 Watt) (15 sec)

W = 3,900,000 Watt-sec

W = 3,900,000 Joules                              (Since Joules = Watt-sec)

W = 3.9 x 10⁶ Joules

a and b sometimes have a positive value
