Question

A block slides down a frictionless plane having an inclination of θ = 15.2°. The block starts from rest at the top, and the length of the incline is 2.80 Determine the acceleration given this system.

Answer 1

The acceleration given this system

$F_x=mg\sin(15.2°)=ma\to a=g\sin(15.2°)=2.57m/s^2$
