Problem Statement
A race car accelerates uniformly from 25 m/s to 50 m/s in 5 seconds. Determine the acceleration of the car and the distance traveled.
Solution
Acceleration a = (50-25)/5
a = 5 m/s2
To find out the distance travelled we will use the equation
V2 = U2 + 2 a S
where S=( V2 – U2 ) /2 a
S = (502 – 252)/(2 . 5) = 187.5 m
