a car accelerates at a constant rate of change of velocity and 5 seconds from 10 M per seconds to 25 m per seconds on highway what is the acceleration and how far does the car this time interval? give a graphical solution.

change in velocity (v2 - v1) = 25mps - 10mps
= 15mps
time taken (t) = 5 s
acceleration (a) = change in velocity/time taken
= 15/5
= 3m/s²
distance (s) = v1t + 1/2at²
= 10(5) + 1/2(3)(5²)
= 50 + 75/2
= 175/2
= 87.5 m
= 15mps
time taken (t) = 5 s
acceleration (a) = change in velocity/time taken
= 15/5
= 3m/s²
distance (s) = v1t + 1/2at²
= 10(5) + 1/2(3)(5²)
= 50 + 75/2
= 175/2
= 87.5 m
