Q1. A car starts from rest and travels for 10s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform negative acceleration of -2.0 m/s2. If the brakes are applied for 3.0s, how fast is the car going at the end of the braking period, and how far has it gone?

Q2. A circular disk with a rectangular hole has a radius of 0.670 m and mass of 0.360 kg. It is suspended by a point on its perimeter. The moment of inertia about this point is I_p = 1.50E-1 kg*m2. Its center of mass is located at a distance of s=0.150 m from the center of the circle as shown. If the disk is allowed to oscillate side to side as the pendulum, what is the period of oscillations?
