The time taken by the sled to reach 45 m to the bottom is 4.24 s.
The sled's initial velocity <em>u</em> is zero. It has an acceleration <em>a</em> of a value 5 m/s² down the hill and it travels a distance <em>s</em> equal to 45 m down the hill.
Use the equation of motion,
Substitute 0 m/s for u and rewrite the equation for t.
The sled takes a time of 4.24 s to reach the bottom of the hill
