Question

A sled starts from rest,
and slides 10.0 m down a 28.0°
frictionless hill. What is its
acceleration?
(Unit = m/s2)

Answer 1

Answer:

The acceleration of the sled is $4.6\ m/s^2$.

Explanation:

It is given that,

Initial speed of sled is 0 because it was at rest.

It is placed at an angle of 28° on a frictionless hill.

We need to find the acceleration of the sled. It is placed at an incline. It means that the acceleration of the sled is given by :

$a=g\sin\theta\\\\a=9.8\times \sin(28)\\\\a=4.6\ m/s^2$

So, the acceleration of the sled is $4.6\ m/s^2$.
