A pendulum with a 1.0 m length and a 2.0 kg mass is given an initial angle of θ0 = 10◦ . Due to air resistance, the mass loses 0.05 J of energy between when it begins moving and when it crosses through equilibrium. With what speed does it cross equilibrium? [Hint: you can convert angle to height by using the formula h = L(1 − cos θ). Use this to find the initial gravitational potential energy.]
Can you draw a picture to help explain this as well as solve it

A pendulum of length L = 1.0 meter and bob with mass m = 1.0 kg is released from rest at an angle 0 = 30' from the vertical. When the pendulum reaches the vertical position, the bob strikes a mass M= 3.0 kg that is resting on a frictionless table that has a height h = 0.85m. (a). When the pendulum reaches the vertical position, calculate the speed of the bob just before it strikes the box. (6 marks]...
