A jet plane has a takeoff speed of vto = 75 m/s and can move along the runway at an average acceleration of 1.3 m/s2. If the length of the runway is 2.5 km, will the plane be able to use this runway safely? Defend your answer.
In a test run, a certain car accelerates uniformly from zero to 24.0 m/s in 2.95 s.
(a) What is the magnitude of the car's acceleration?
(b) How long does it take the car to change its speed from 10.0 m/s to 20.0 m/s?
(c) Will doubling the time always double the change in speed? Why?
A car starts from rest and travels for 5.0 s with a uniform acceleration of 1.5 m/s2. The driver then applies the brakes, causing a uniform acceleration of -2.0 m/s2. If the brakes are applied for 3.0 s,
(a) How fast is the car going at the end of the braking period?
(b) How far has the car gone?
In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 71.5 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.0 s in the pit and then accelerates out, reaching her previous speed of 71.5 m/s after a distance of 350 m. At this point, how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
An object is moving with a constant velocity of 10 m/s. What is its acceleration?
0 m/s²
5 m/s²
10 m/s²
15 m/s²
A dog basks in the sun when he sees a squirrel and bolts after it. If the dog accelerates at +1.6 m/s/s, how far does he run in 3 seconds?
4.8 meters
45 meters
1.6 meters
7.2 meters
