if a 10 kg object has a kinetic energy of 20 J what is its speed and what is the formula used to calculate speed

A uniform rod is 2.0 m long. The rod is pivoted about a horizontal, frictionless pin through one end. The moment of inertia of the rod about this axis is given by (1/3) ML2. The rod is released from rest at an angle of 30° above the horizontal.

In uniform circular motion, the acceleration is perpendicular to the velocity at every instant. Is this true when the motion is not uniform-that is, when the speed is not constant?
