1. A 2500 kg van moving to the right with a speed of 10m/s collides with a stationary food cart that is 1000 kg. After the collision, the food cart moves 5m/s. Calculate the final velocity of the van. 2. A simple pendulum Im long has a 5 kg bob. a) Calculate the work done by an outside force in pulling the pendulum from a vertical to a horizontal position. b) If the pendulum is then released. What will be the speed of the bob as it passes through the lowest point of its path? 3. A car travels from city ABC to city XYZ at an average speed of 60 mph. The car travels an average speed of 50 mph on the return trip back to city ABC. If the distance between the two cities is 300 mile. What is the average speed of the car for the entire trip? 4. Jon runs 8 m North, 8 m West, 8 m South, 23 m East, and 8 m South. Find the distance covered. 5. Using the given values in number 4, find Jon's displacement
