Please assist with 1 and 2. thanks!

1) A large pulley (solid disk) of mass 5.0 kg and radius 12 cm has a string 12 cm wrapped around it. A 34-N force is pulling it as shown to the right. Find the magnitude and direction of the angular acceleration of the pulley. 5 kg 34 N 2) A football player is doing pull-ups. As he tires, he hangs stationary, with his elbows at 90 degrees (this is #998). He has a mass m = 80 kg. L and his forearm and upper arm each have the same length L = 35 cm. His biceps tendon is attached a distance d = 5 cm from his elbow joint. Find the tension in his biceps tendon. (Don't forget that he has 2 arms!) L m
