# How do I find the magnitude of acceleration?

A 3 kg block starts from rest at the top of a 30 degree incline and slides a distance of 1.90m down the incline in 1.60s. What is the magnitude of the acceleration of the block?

Use $s = ut + \frac12 at^2$

s is the distance travelled,
u is the initial speed,
t is the time,
a is the acceleration.

Solve for a.
