प्रश्न
Write an expression for the distance S covered in time t by a body which is initially at rest and starts moving with a constant acceleration a.

उत्तर
Distance = s, time = t, initial velocity u = 0 and acceleration = a.
Using the second equation of motion and substituting the above values we get,
s = ut + (1/2) at2
s = `1/2 "at"^2`
