Question

A car starts from rest and moves along the x-axis with constant acceleration 5 M per second square for 8 second if it then continue with constant velocity what distance will the car cover in 12 s since it started from rest

Answer 1

Initial velocity u = 0 m/s
Acceleration a = 5 m/s²
total time t = 12 s
$s = ut + \frac{1}{2} a {t}^{2} \\ \: \: \: = 0 + \frac{1}{2} \times 5 \times {12}^{2} \\ \: \: \: = 360 \: m$
