Kinematics practice problems
At the scene of an accident a police officer notices that the skidmarks of a car are 10 m long. The officer knows
that the typical deceleration of this car when skating is -45 m/s squared what can the officer estimate for the
original speed of the car. - correct answer30 m/s
Starting from rest the Road Runner accelerates at 3 mi./s for 10 seconds what is the final velocity of the road
runner - correct answer30 mi./s
Starting from rest the road runner accelerates at 3 mi./s for 10 seconds how far does the Road Runner travel
during the 10 second time interval - correct answer150 miles
A bullet start from rest accelerates at 4000 m/s² down a .5 m long barrel what is the velocity of the bullet as it
leaves the barrel of the gun - correct answer200 m/s
A car traveled at 20 m/s applies its brakes and comes to a stop in four seconds what is the acceleration of the
car - correct answer-5 m/s squared
A car traveling at 20 mi./s applies its brakes and comes to a stop in four seconds how far does the car travel
before coming to a stop - correct answer40 m
The USS enterprise accelerates from rest at 100,000 m/s squared Siri timer for seconds. How far did the ship
travel in that time - correct answer800,000 m
A skier traveling at 5 m/s accelerates down a hill at 1 m/s squared for three seconds. what is the final velocity
of the skier and how far down the hill has the skier traveled in this time. - correct answer8 m/s squared,
displacement is 67.5 m
