Q1. A goldfish in a spherical fish bowl of radius R is at the level of the center C of the bowl and at distance L = R/2.8 from the glass. What magnification of the fish is produced by the water in the bowl for a viewer looking along a line that includes the fish and the center, with the fish on the near side of center? The index of refraction of the water is 1.33. Neglect the glass wall of the bowl. Suppose the viewer looks with one eye.

Q2. A bullet of mass 0.0022 kg initially moving at 496 m/s embeds itself in a large fixed piece of wood and travels 0.64 m before coming to rest. Imagine that an acceleration of the bullet is constant.

Q3. A snowmobile is initially at the point with position vector 26.3 m at 95.0° counter clockwise from the x axis, moving with velocity 4.29 m/s at 40.0°. It moves with constant acceleration 1.92 m/s2 at 200°. After 5.00 s have elapsed, find the following.
