A500 kg horse can provide a steady output power of 750 w (that is, 1 horsepower) when pulling a load; how about a 38 kg sled dog? data shows that a 38 kg dog can pull a sled that requires a pulling force of 60 n at a steady 2.2 m/s.

1. what is the specific power for the dog and the horse?
2. what is the minimum number of dogs needed to provide the same power as one horse?

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
