Aspeeder doing 40.0 mi/h (about 17.9 m/s) in a 25 mi/h zone approaches a parked police car. the instant the speeder passes the police car, the police begin their pursuit. if the speeder maintains a constant velocity, and the police car accelerates with a constant acceleration of 4.51 m/s2, (a) how much time does it take for the police car to catch the speeder, (b) how far have the two cars traveled in this time, and (c) what is the velocity of the police car when it catches the speeder?
a) 7.96 s b) 143m c) 35.8 m/s

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
