Question

A car accelerates from 4.0 m/s to 24 m/s at a rate of 2.5m². How far does it travel while accelerating?

A) 69m B) 207m C) 41m D) 112m E) 980m

Equations to chose from:

x=x_o+V_of +1/2at²

V=v_o+at

V²=V_o²+2a(x-x_o)

Answer 1

Answer #1

Using equation,

V^2 = u^2 + 2a(x - xo)

24^2 = 4^2 + 2 x 2.5 x X

24^2 - 4^2 = 5 x

X = 112 m
