Question

A car moving westward along a straight, level road increases its velocity uniformly from +19 m/s to +35 m/s in 10.2 s.How far did it move while accelerating? Answer in units of m.

Answer 1

According to the equations of the motion
V=V₀ + at
x = x₀ +V₀t +at²/2
Thus
a = (V-V₀)/t = (35-19)/10.2 = 1.57 m/s2
x = 0 + 19*10.2 + 1.57*10.2²/2 = 245.47 m.

Answer: 245.47 m.
