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

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

Step-by-step 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* \sin(28)\\\\a=4.6\ m/s^2`

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