Answer:

Time, t = 4.862 seconds

Explanation:

Given the following data;

Initial velocity = 0

Acceleration = 1.1m/s²

Distance = 13m

To find the time, we would use the second equation of motion;

S = ut + ½at²

Substituting into the equation, we have;

13 = 0*t + ½*1.1*t²

13 = 0.55t²

t² = 13/0.55

t² = 23.64

Taking the square root of both sides, we have;

Time, t = 4.862 seconds
