A 5-kg object travels at 10 m/s before it collides with a another object. After it collides, it travels in the direction opposite to which it travelled before the collision, but at 5 m/s. The collision takes 0.05 seconds. 1. What is the mometum of the 5-kg object before the collision?

2. What is the momentum after the collision?

3. What is the change in momentum of the 5-kg object?

4. How much force was exerted on the 5-kg object during the collision? Use the equation

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
