Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does that mean that the acceleration of car A is greater than that of car B? Explain.
Acceleration is the change in velocity over time. Given this information, is acceleration a vector or a scalar quantity? Explain.
A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.
Lisa in her Lamborghini accelerates at (3.00i2.00j)m/s2, while Jill in her Jaguar accelerates at (1.00i3.00j)m/s2. They both start from rest at the origin. After 5.00 s, (a) what is Lisas speed with respect to Jill. (b) how far apart are they, and (c) what is Lisas acceleration relative to Jill?
Construct the displacement graph for the subway shuttle train as shown in Figure 2.18(a). Your graph should show the position of the train, in kilometers, from t=0 to 20 s. You will need to use the information on acceleration and velocity given in the examples for this figure.
Kathy tests her new sports car by racing with Sian, an experienced racer. Both start from rest, but Kathy leaves the starting line 1.00 s after Stan does. Stan moves with a constant acceleration of 3.50 m/s2, while Kathy maintains an acceleration of 4.90 m/s2. Find (a) the time at which Kathy overtakes Stan, (b) the distance she travels before she catches him, and (c) the speeds of both cars at the instant Kathy overtakes Stan.
An object that is thrown straight up falls back to Earth. This is one-dimensional motion. (a) When is its velocity zero? (b) Does its velocity change direction? (c) Does the acceleration clue to gravity have the same sign on the way up as on the way clown?
A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 11.5 m/s and accelerates at the rate of 0.500 m/s2 for 7.00 s. (a) What is his final velocity? (b) The racer continues at this velocity to the finish line. If he was 300 m from the finish line when he started to accelerate, how much time did he save? (c) One other racer was 5.00 m ahead when the winner started to accelerate, but he was unable to accelerate, and traveled at 11.8 m/s until the finish line. How far ahead of him (in meters and in seconds) did the winner finish?
A graph of v(t) is shown for a world-class track sprinter in a 100-m race. (See Figure 2.67). (a) What is y1his average velocity for the first 4 s? (b) What is his instantaneous velocity at t=5 s? (c) What is his average acceleration between 0 and 4 s? (d) What is his time for the race?
A speedboat moving at 30.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of -3.50 m/s2 by reducing the throttle, (a) How long does it take the boat to reach the buoy? (b) What is the velocity of the boat when it reaches the buoy?
. A rock is dropped off the side of a bridge and hits the water below 2 s later. (a) What was the rock's velocity when it hit the water? (b) What was the rock's average velocity as it fell? (c) What is the height of the bridge above the water?
