A dog runs in a straight line for 50 meters in 12 seconds chasing a pheasant. The dog then freezes and points at the bird for 10 seconds. The bird flies away and the dog spends another 15 seconds trotting back to his starting point. What was the magnitude of the dogs average velocity in m/s during this encounter

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
