Question:
Three sled-dogs pull on a sled on snow. The sled is initially moving at a speed of 12.5 m/s when the dogs start pulling harder for about 1.25 s, causing the sled to move with a final speed 18.0 m/s. If the sled has a total mass of 458 kg, what is the force exerted by the dogs on the sled in this time interval?
