Question

A car accelerates from rest along a straight road and its distance from the starting point is given by the equation $S = \frac{5}{4} t^{2}$ , where $S$ is the distance in meters and $t$ is the time in seconds. If the car needs to reach a speed of $90 km slash h$ to safely merge onto a highway, how long will it take to reach this speed, and what distance will the car cover?

Accepted Answer

$10 s$

$S\left(10 ight)=125~ ext{m}$

Answer

$10 s$

$S of 12 equals 180 m$

Answer

$10 s$

$S of 12 equals 180 m$

Answer

$10 s$

$S of 12 equals 180 m$
