Physics: centripetal acceleration, tangential acceleration, and angles?

Jeff of the Jungle swings on a vine that is 7.20m long (see the figure). At the bottom of the swing, just before hitting the tree, Jeff's linear speed is 8.5m/s. Suppose that at some point in his swing Jeff of the Jungle has an angular speed of 0.890rad/sec and an angular acceleration of... show more Jeff of the Jungle swings on a vine that is 7.20m long (see the figure). At the bottom of the swing, just before hitting the tree, Jeff's linear speed is 8.5m/s. Suppose that at some point in his swing Jeff of the Jungle has an angular speed of 0.890rad/sec and an angular acceleration of 0.690rad/sec^2.
Find:
The magnitude of his centripetal acceleration in m/s^2.
The magnitude of his tangential acceleration in m/s^2.
The magnitude of the total acceleration in m/s^2.
The angle his total acceleration makes with respect to the tangential direction of motion in degrees.

Thanks!
