A 0.75 kg toy car moving with a speed of 3 m/s to the right collides with a 0.25 kg toy car moving with a speed of 3 m/s to the left. The two collide and the 0.25 kg toy car ends with a speed of 5 m/s to the right. What is the final speed of the 0.75 kg car? Is this collision elastic? Explain.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
