Problem Set A


The following selection of problems are sample problems. Individual student problem sets will vary since numerical information is randomly-generated.



For the following problems:



Problem 1:

Seeing the light turn yellow, Willie Makeit gives it the gas and accelerates from +15.0 m/s to +23.1 m/s in 2.4 seconds. Determine the average acceleration of Willie's car.


Problem 2:

A rightward moving car slams on the brakes and slows down from 31.2 m/s to 4.9 m/s in 3.87 seconds. Determine the average acceleration of the car.


Problem 3:

A race car accelerates from rest to a speed of 49.4 m/s in 4.97 seconds. Determine the distance traveled during this time period.


Problem 4:

A train is accelerated uniformly from 13.1 m/s to 36.2 m/s in 8.2 s. Determine the displacement of the train.


Problem 5:

Starting from rest, a car moves 102.5 m in 6.2 s. Determine the car's average acceleration.


Problem 6:

A bicyclist is at the crest of a hill and moving with a speed of 11.2 m/s. If she accelerates at a rate of 1.12 m/s/s, then what is her displacement after 9.3 seconds.


Problem 7:

Luke Autbeloe drops a stone into a well. The stone splashes into the water below after falling for a time of 4.8 seconds. The stone accelerates at a rate of -9.8 m/s/s. Determine the depth of the well (absolute value only; no + or - sign).


Problem 8:

A golf ball rolls up a long hill on a miniature golf course. It starts with a speed 3.2 m/s and accelerates at a uniform rate of -.8 m/s/s. Determine its velocity after 1.75 seconds.


Problem 9:

An airport engineer is assigned the task of designing a run-way which accomodates airplanes which reach a takeoff speed of 68.8 m/s. If the planes are capable of accelerating at a constant rate of 3.2 m/s/s. Determine the minimum length required to allow the airplanes to take off.


Problem 10:

Car A and Car B are separated by a distance of 62.5 meters and are traveling with a speed of 31.2 m/s. Car A - the lead car slams on its brakes and accelerates at -9.3 m/s/s. Car B slams on its brakes at exactly the same time and accelerates at -8.5 m/s/s. Determine the distance between cars upon coming to a stop.
