# Accleration and angle

Please help me with this question. I understand how to calculate the velocity from the given conditions but I don't know how to figure out the acceleration or the angle. Thanks!

A cart is released from rest at the top of a perfectly frictionless air track. After an elapsed time delta t = 2.0s, the cart has traveled delta x = 32.0 cm down the track. What is the cart's acceleration? What is the angle of theta of this track?

The acceleration of the cart is the component of its weight parallel to the track divided by its mass so $a = g \cos \theta$. The distance it travels is
$$d = \frac {1}{2} a t^2$$
