9. A speeder traveling at 42 m/s passes a motorcycle policeman at rest at the side of the road. The policeman accelerates at 3.23 m/s2. To the nearest tenth of a second how long does it take the policeman to catch the speeder? 10. How far to the nearest tenth of a meter can a runner running at 12 m/s run in the time it takes a rock to fall from rest 56 meters?

A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The Ford moves at a constant speed of 49.9 m/s. Just as the Ford passes it, the Toyota is traveling at 17.9 m/s. As soon as the Ford passes the Toyota, the Toyota begins to accelerate forward at a constant rate. Meanwhile the Ford just keeps going at a steady [] m/s to the east. The Toyota catches up to the Ford a distance...

A red car and a green car are traveling along a straight road in the same direction. The red car's position is given by x(t)=t3 and the green car is accelerating at a constant rate. At time t = 0, the green car is 132 m ahead of the red car. At t = 2 s, the red car reaches the same speed as the green car, and at t = 6 s, the red car catches up to the...

Review Interactive LearningWare 2.2 in preparation for this problem. A police car is traveling at a velocity of 17.0 m/s due north, when a car zooms by at a constant velocity of 45.0 m/s due north. After a reaction time 0.800 s the policeman begins to pursue the speeder with an acceleration of 6.00 m/s 2. Including the reaction time, how long does it take for the police car to catch up with the speeder? Vp North -- Police car...

A car is initially stopped, vco = 0, at a traffic light whose
position we will use as our origin, x = 0. The light turns green at
time t = 0 and the car starts moving with constant acceleration ac
= 2 m/s2 . At that same instant, the front of a truck traveling at
constant speed vt = 15 m/s passes the front of the car. After a
time tD and distance x = D, the accelerating car...

12-10. Car A starts from rest at t-0 and travels along a straight road with a constant acceleration of 3 m/s until it reaches a speed of 27 m/s. Afterwards it maintains this speed. Also, when-0, car B located 2000 m down the road is traveling towards A at a constant speed of 20 m/s. Determine the distance travelled by car A when they pass each other. 20 m/s 2000 m 12-11. A particle travels along a straight line with...
