A 40.0-g ice cube floats in 200 g of water in a 100-g copper cup; all are at a temperature of 0C. A piece of lead at 98.0C is dropped into the cup, and the final equilibrium temperature is 12.0C. What is the mass of the lead?

Rotational Kinematics and Energy Rotational Kinematics ● A relationship exists between linear and angular quantities. To do this all angles have to be measured in radians. ● Analogies: ○ Linear Angular Position x (position) θ (radians) Velocity v (velocity) ω(angular velocity) Acceleration a (acceleration) α(angular acceleration) Force F (force) τ (torque) Mass m (mass) I (moment of inertia) ○ ○ COUNTERCLOCKWISE IS POSITIVE
