2m 20 1m You have built an enormous spring-loaded Hot Wheels track that will propel a 50 gram toy car through a loop and launch it across the room. The spring constant is 800 N/m, the spring launcher has an initial spring displacement of 5 cm. What is the maximum radius R of the loop such that the car moves around the loop without falling off at the top, so that the toy car can make to the end point...

Procedure: Materials: 1. apparatus 2. 2 pieces of metal track 3. plastic or metal ball 4. timer 5. meter stick 6. micrometer 7. 2 photogates Assemble your ramp as shown in Figure (1) in the next page. Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...
