A tiger runs one kilometer. The tiger does 15,000 j of work and has a total power output of 500 w. How many seconds soes it take the tigar to run the distance?

What's the acceleration if the average velocity is 3.5 and the time is 8.7

A closed system consisting of 2 lb of a gas undergoes a process during which the relation between pressure and volume is pVn = constant. The process begins with p1 = 15 lbf/in. 2, ν1 = 1.25 ft3/lb and ends with p2 = 60 lbf/in. 2, ν2 = 0.5 ft3/lb.
