... 4.5 cm in a tree. Subsequent measurements showed that the tree would exert a stopping force of 70N on the straw. What was the straw’s speed when it hit the tree? Since the stopping force (70 N) is so much larger than the weight of the straw (0.0049 N), we may assume that the net work done is essenti ...

... On the downward parts of the trip, the gravitational force does positive work, increasing the car’s kinetic energy and ultimately increasing its “speed”. Conversely, on the upward parts of the motion, the gravitational force does negative work, decreasing the car’s kinetic energy as well as decreas ...

... Check: (a) 0.8 nm is an atomic-scale separation, so we should not be surprised that some velocity has been lost – i.e. our answer is in the right ballpark, 0 < v < initial velocity. (b) 2.8 10–10m is 0.28 nm which is >0 and < the distance of part (a), so again in the right ballpark. (c) This is a ...
