10. Move the Motion Sensor. Place the Motion Sensor at the bottom of the track pointing up the track. 11. Check the Motion Sensor. Start with the cart at least 50 em in front of the sensor. Practice pushing the cart up the track so the cart doesn't go over the top of the track and stopping the cart before it gets within the 50 em of the sensor. Start the sensor and push the carit up the track. Stop...

A proposed ride at the Valley Fair amusement park launches a roller coaster car up an inclined track. Near the top of the track, the car reverses direction and rolls backwards into the station. As a member of the safety committee, you have been asked to compute the acceleration of the car throughout the ride and determine if the acceleration of an object moving up a ramp is different from that of an object moving down the same ramp. To...

Two carts are riding on an air track as shown in the figure. At time t = 0 s, cart B is at the origin and traveling in the negative x direction with velocity v_B1. At that time, cart A is at the position shown and is at rest. Car B has twice the mass of cart A. The carts "bump" into each other but do not stick. Which physical parameter can be described by each of the following graphs?...

please help with #7 and question 6 (the last question)
3. Rescale the axes if necessary to see all of the graphs. Answer the following questions: a. At the instant the push ends, what does the force equal? F= b. At the instant the push ends, what does the acceleration equal? a= c. At the instant the push ends, what can you say about the speed of the cart? Look carefully at the graphs on the computer monitor. 4. Use...
