Please answer ASAP. A 25.0 kg dog decides to go for a solo hike to the top of a 850.0 m tall mountain. 1. How much work does the dog do? 2. If the dog walks along the trail and covers a distance of 2550 m, what is the average force exerted by the dog? 3. Imagine there is a second dog with the same mass that decides to walk the trail but takes an alternative route that zigzags back and forth (its a much easier walk). Which dog does more work?

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.
