motion and torque

Problem 1
a person stands on a platform 10 meters high, and throws an object at 14 m/s at 45 degrees.
1. how high did the object go?
2. how long did it travel in the air?
3. how far did it travel?

Problem 2
disk A has a moment of inertia of 6
disk B has moment of inertia of 1.5
angular velocity of disk A is 1.0

1. find the angular velocity of both disk together
2. find kinetic energy of A and B separately
3. what difference cause changes in kinetic energy and angular velocity

    We're not going to do your homework for you. You need to make an attempt, here.
