Find the Ramp Angle for a 3kg Block on a Frictionless Ramp

[vincentp07]

A 3kg block is released from rest at the top of a frictionless ramp 1.5m long. The acceleration of the blick is measured to be 3.8m/s/s. What is the angle x of the ramp?

all answers in degrees

a)x= 12.1
b)x=16.3
c)x=22.8
d)x=25.2
e)x=37.4
