| May 9, 2021 | education
Given:
t = 5 seconds – time interval;
v0 = 0 m / s – initial vehicle speed;
v1 = 15 m / s – the final speed of the vehicle.
It is required to determine a (m / s ^ 2) – vehicle acceleration.
a = (v1 – v0) / t = (15 – 0) / 5 = 15/5 = 3 m / s ^ 2.
Answer: vehicle acceleration is 3 m / s ^ 2.
