Imagine that a sprinter accelerates from rest to a maximum speed of 10.3 m/s in 1.8 s. In what time interval will he finish the 100-m race if he keeps his speed constant at 10.3 m/s for the last part of the race? What assumptions did you make?
Parts (a), (b), and (c) of Figure 2.10 represent three graphs of the velocities of different objects moving in straight-line paths as functions of time. The possible accelerations of each object as functions of time are shown in parts (d), (c), and (f). Match each velocity vs. time graph with the acceleration vs. time graph that best describes the motion. Figure 2.10 (Quick Quiz 2.3) Match each velocity vs. time graph to its corresponding acceleration vs. time graph.
Liz rushes down onto a subway platform to find her train already departing. She stops and watches the cars go by. Each car is 8.60 m long. The first moves past her in 1.50 s and the second in 1.10 s. Find the constant acceleration of the train.
A car travels on a straight, level road. (a) Starting from rest, the car is going 44 ft/s (30 mi/h) at the end of 5.0 s. What is the cars average acceleration in ft/s2? (b) In 4.0 more seconds, the car is going 88 ft/s (60 mi/h). What is the cars average acceleration for this time period? (c) The car then slows to 66 ft/s (45 mi/h) in 3.0 s. What is the average acceleration for this time period? (d) What is the overall average acceleration for the total time? (Note these convenient British unit conversions: 60 mi/h = 88 ft/s, 45 mi/h = 66 ft/s, and 30 mi/h = 44 ft/s.)

A truck tractor pulls two trailers, one behind the other, at a constant speed of 1.00 102 km/h. It takes 0.600 s for the big rig to completely pass onto a bridge 4.00 102 m long. For what duration of time is all or part of the truck-trailer combination on the bridge?
The velocity-versus-time graph for a car driving down a straight road is shown. How far does the car travel during the time interval from t = 0 s to t = 4.0 s?A. 10 m B. 20 m C. 40 m D. 60 m
One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.5 m/s in 2.24 s , what will be his total time? Express your answer in seconds.
Car A is traveling at 11.6 m/s and car B is traveling with a constant speed of 25.0 m/s. Car A is 300 meters behind car B when the driver of car A accelerates his car with a uniform forward acceleration of 2.40 m/s2. From the moment car A begins to accelerate, how long does it take car A to catch up with car B? Write the answer in seconds using three significant figures.
The velocity vs time graph for an object is shown. How far has it gone in 4.5 seconds starting at t = 0s? The figure shows the velocity versus time graph for an object. From t = -3 to 0s, the velocity is constant at 45 m/s. From t=0 to 4.5s, velocity decreases linearly from 45 m/s to 0 m/s. 101 m 225 m 150 m 112 m
At a stop light, a truck traveling at 15 m/s passes a car as it starts from rest. The truck travels at constant velocity and the car accelerates at 3 m/s2. How much time does the car take to catch up to the truck? Group of answer choices 10 s 25 s 15 s 20 s 5 s
A race car moves such that its position fits the relationship x = (5.5 m/s)t + (0.65 m/s3)t3 where x is measured in meters and t in seconds. (b) Determine the instantaneous velocity of the car at t = 3.8 s, using time intervals of 0.40 s, 0.20 s, and 0.10 s. (In order to better see the limiting process keep at least three decimal places in your answer.) Δt = 0.40 s m/s (Use the interval from t = 3.60 s to 4.00 s.) Δt = 0.20 s m/s (Use the interval from t = 3.70 s to 3.90 s.) Δt = 0.10 s m/s (Use the interval from t = 3.75 s to 3.85 s.)
