1. You observe a dime (m = 2.3 grams) come to a stop from speed vi = 14.2 m/sec, over a distance Δx = 3.093 m.

Calculate: the size of the average stopping force on the dime.

2. You measure the times and distances of an apple (mass m =0.14k g) travelling left to right, and then you compute its speed, which is 4.9m s.

Calculate its kinetic energy to the nearest 0.1 Joule.

You observe and video a little kid take a spill and slide to a stop at the skating rink. By analyzing the video on your cell phone, you know the little kid's mass was m = 40 kg, and his initial speed was vi = 4.5 m/sec. Furthermore, your uncle runs the rink, so you know the friction force f on the little kid: f = 20.3 N. Calculate: the stopping distance to the nearest 0.1 m. E.g., if your...
