A boy whose weight is 600 N runs up a flight of stairs 10m high in 12 s. What is his average power?

You carry a 7.0-kg bag of groceries 1.2 m above the ground at constant speed across a 2.7m room. how much work do you do on the bag in the process? (a) 157j (b) 0.00j (c) 185j (d) 82j

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
