Question

Assuming equal rates of acceleration in both cases, how much further would you travel if braking from 52 mi/h to rest than from 26 mi/h?

A) 8 times further B) 2 times further C) 4 times further D) Same distance E) Not enough information

Equations to choose from:

x=x_o+V_of +1/2at²

V=v_o+at

V²=V_o2+2a(x-xo)
