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.
