The brakes of a 125 kg sled are applied while it is moving at 8.1 m/s, which exerts a force of 261 n to slow the sled down. how far does the sled travel while coming to a stop in meters? round to one decimal place.

15.7 m

Explanation:

m = mass of the sled = 125 kg

v₀ = initial speed of the sled = 8.1 m/s

v = final speed of sled = 0 m/s

F = force applied by the brakes in opposite direction of motion = 261

d = stopping distance for the sled

Using work-change in kinetic energy theorem

- F d = (0.5) m (v² - v₀²)

- (261) d = (0.5) (125) (0² - 8.1²)

d = 15.7 m

the answer is c.)
