Question

A boy starting from rest, slides down a snowy hill on a sled. He travels 174.19 m to the bottom of the hill. He accelerates
down the hill at 2.61 m/s^2. How long does it take the boy to get to the bottom of the hill?

Answer 1

Answer:

11.6 s

Explanation:

We can use equation of motiom to solve this

$s = ut + \frac{1}{2} a {t}^{2 } \\ 174.19 = (0)t + \frac{1}{2} (2.61){t}^{2 } \\ t = 11.6s$
