Answer:
The acceleration of the sled is
.
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](https://img.qammunity.org/2021/formulas/physics/college/qefbhxn51s8nr0eeszhc3a2xiw3adphyrr.png)
So, the acceleration of the sled is
