A bar on a hinge starts from rest and rotates with [tex]\alpha[/tex]=(10+6t) rad/s^{2}t is in seconds. Determine the angle in radians the bar turns in the first 4 seconds.

2. Relevant equations

I'm a little stumped how to get this one started. I assume i need to get it from angular acceleration to angular displacement, but I'm not exactly sure how to do that. So do I have to integrate it with respect to time twice?

3. The attempt at a solution
