You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.73 s, and the velocity of the car decreases to + 5.37 m/s. The car’s deceleration has a magnitude of 3.02 m/s2 during this time. What is the car’s displacement? x =

A dynamite blast at a quarry launches a rock straight upward, and 1.8 s later it is rising at a rate of 10 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 4.4 s after launch.

Concept Simulation 2.3 provides some background for this problem. A ball is thrown vertically upward, which is the positive direction. A little later it returns to its point of release. The ball is in the air for a total time of 8.36 s. What is its initial velocity? Neglect air resistance. v0 =

Concept Simulation 2.3 offers a useful review of the concepts central to this problem. An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +21.2 m/s and measures a time of 18.4 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (positive = up, negative = down)

A hot-air balloon is rising upward with a constant speed of 3.78 m/s. When the balloon is 9.24 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground? From her bedroom window a girl drops a water-filled balloon to the ground, 8.93 m below. If the balloon is released from rest, how long is it in the air?

A driver spots a huge pothole ahead and hits her brakes, and the car accelerates at -20 m/s ^2. Please pay attention to the mass of the car because two experts changed it to 1.250kg and it is 1,250kg. Also explain the math. Thanks. A. If the car’s mass is 1,250 kg, what is the net force on it? B. What applies the force on the car that causes it’s deceleration? C. If the driver’s mass is 60 kg, what...

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 4.7 m/s2 for 3.8 seconds. It then continues at a constant speed for 8.5 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 206.78 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

You are in your car A on the 407 driving at a constant velocity ~vA = (vA, 0, 0) and next to it another car (B) takes the exit ramp on one of Toronto’s huge exchangers to get onto the 404. For consistency we set the two cars to start at (0, 0, 0) at t = 0 and car B turns in the positive y direction. The exchanger can be seen as a quarter circle of radius R. 1....
