1) A bridge is built in the shape of a parabolic arch. The bridge arch has a span of 180 feet and a maximum height of 30 feet. Find the height of the arch at 20 feet from its center. 2) A searchlight is shaped like a paraboloid of revolution. If the light source is located 3 feet from the base along the axis of symmetry and the opening is 8 feet across, how deep should the searchlight be?

Can someone help me with number 2. Thank you . A van traveling 60 mi/hr sees a duck in the distance and slams on its brakes. If the duck is exactly 3 feet away when the van begins braking, how quickly must it accelerate in order to save c.

Please work out 3 clearly and with units. Thanks! 1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...
