7. For each of the motions below sketch a motion diagram as described in section You may use a dot to represent the object in motion. First, establish a coordinate axis for each motion. Draw arrows to scale above each dot to represent the velocity vector. Indicate the acceleration direction for each constant acceleration segment of the motion.

Item 3 Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 4.0 m/s. Once free of this area, it speeds up to 13 m/s in 8.0 s. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 s to reach a higher cruising speed. Learning Goal: To practice Problem-Solving Strategy...

Write down relevant equations, draw diagrams and show all of your work for full credit. 1. (20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip.

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop?

Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...
