Homework Statement


A 3.86 kg block slides down a smooth, fric-
tionless plane having an inclination of 28◦ .
The acceleration of gravity is 9.8 m/s2 .

Find the acceleration of the block.
Answer in units of m/s2.


Homework Equations


idk what equation to use?


The Attempt at a Solution

 
Physics news on Phys.org
Newton's 2nd law. Choose the x-axis parallel to the incline, and identify the force acting parallel to the incline. Then apply Newton 2 in the direction of the incline.
