A block slides down a frictionless, inclined plane that makes a `30^(@)` angle with the horizontal. Find the acceleration of this block.

Text Solution

Verified by Experts

Let m be the mass of the block, so the force that pulls the block down the incline is `mg sin theta`, and the block's acceleration down the plane is
`a= (F)/(m)=(mg sin theta)/(m)= g sin theta= g sin 30^(@)=(10)xx(0.5)=5 m//s^(2)`
