Question: a dog runs happily througn lelul for 050 ms for...

Question details

A dog runs happily througn lelu.l for 0.50 m/s for 2 min, and then turns due east and runs at 2.0 m/s tor3 I What is the average speed of the dog? What is the average velocity? a. b. ) child is pulled along the flat ground on snow on a sled by his father. The chi together have a mass of 33 kg. The father pulls the sled by a rope which is angled upward at a 40 degree angle above the horizontal. If the coefficient of friction between the snow and the led is 16, determine the force the father must pull with to maintain constant velocity. (you must nd the Normal Force and the friction Force) before you can solve this ld and sled
