Q1. A woman is riding a boat at the speed of v when she notices a seawall straight ahead. The farthest she can lean the boat in order to make a turn at an angle. She makes a turn without slowing down. This situation is like that of a car on a curve that is banked at an angle. Illustrate that the least distance from seawall that she can cover before making a turn is v.v/gtantheta

Q2. A harmonic wave travels in a wire with amplitude 6.05 mm, wavelength 0.451 m, and frequency 462 Hz. What is speed with which the wave travels?

Q3. The Doppler shift was first tested in 1845 by the French scientist B. Ballot. He had a trumpet player sound a 390 Hz note while riding on a flat-car pulled by a locomotive. At the same time, a stationary trumpeter played the same note. Ballot heard 4 beats/s.

How fast was train moving toward him? The speed of sound in air is 343 m/s.
