16) You are in the left lane (speeding) at 40 m/s when you notice a police car ahead of you traveling at 30 m/s (the speed limit). When you are 45 m apart you start decelerating at 1.0 m/s2. Will you pass the police car and get a ticket? 17) A car is traveling at 25.0 m/s approaching a bicyclist moving at 7.0 m/s in the same direction. There is 75 m between them when the driver hits the brakes....

While driving along the highway at 40 m/s, you spot a police car 50 m ahead, traveling at a constant speed of 25 m/s which is the speed limit. You apply brakes and begin decelerating at 2 m/s2 A. Determine the time/s that you and the police will pass each others car. B. Assume that the police will give speeding ticket at the first instance that you passed each others car, will you get a...

12) A sprinter running a 100 m race starts at rest and accelerates at constant acceleration A for 3.0 seconds and then maintains a constant velocity. In terms of A, what is the position of the runner after 3.0 seconds? What is A if the sprinter finishes the race in 12.0 seconds? 13) What force is needed to accelerate a 30.0 lb block at 2.2 m/s2? 14) What force is needed to stop a 1500 kg car in 40 m...

Frank, driving at 30.0 m/s, enters a one-lane tunnel. He then observes a slow-moving van 150.0 meters ahead traveling with speed 1.0 m/s (because it has engine trouble). He applies the brakes immediately to decelerate at a constant rate but still hits the van. From the damage, it is determined that he was traveling at 5.0 m/s when the collision occurred. Determine the magnitude of Frank's deceleration as he applied the brakes.

. A van traveling 60 mi/hr sees a duck in the distance and slams on its brakes. If the duck is exactly 3 feet away when the van begins braking, how quickly must it accelerate in order to save c. A duck on a motorcycle is speeding down the highway at 65 mi/hr where the speed limit is 00 the duck? only 55 mi/hr. It passes a police car on the...

Speedy Sue, driving at 35.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 160 m ahead traveling at 5.50 m/s. Sue applies her brakes but can accelerate only at −1.90 m/s2 because the road is wet. Will there be a collision? If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van. (If no, enter "0" for the time.)

Question 1 5 pts Consider two cars traveling on the highway, one behind the other. They are both moving at the same initial velocity, v 29.1 m/s, with the first car a distance d in front of the second car. ("d" is the distance from the front bumper of the second car to the back bumper of the first car.) At some time the driver of the first car hits the brakes and comes to a stop with...

Refer to Multiple-Concept Example 5 to review a method by which this problem can be solved. You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.24 s, and the velocity of the car decreases to4.87 m/s. The car's deceleration has a magnitude of 3.08 m/s2 during this time. What is the car's displacement? the tolerance is +/-590
