Answer to Question #1458 in Mechanics | Relativity for Janina
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.
According to the equations of the motion
V=V0 + at
x = x0 +V0t +at2/2
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.
