Kinematics Basics
A dragster accelerates to a speed of 112 m/s over a distance of 398 m. Determine the acceleration of the dragster.
a = 15.8 m/s/s
Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the acceleration and what is the distance that the sled travels?
a = 243 m/s/s, d = 406 m
An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.
d = 1720 m
A bike accelerates uniformly from rest to a speed of 7.10 m/s over a distance of 35.4 m. Determine the acceleration of the bike.
d = 704 m
It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s2, determine the speed of the Jaguar before it began to skid.
vi = 47.6 m/s
The three kinematic equations
x=vit+1/2at^2 , vf^2=vi^2+2ax , vf=vi+at
