Waves moving on a lake have a speed of 1.6 m/s and a distance of 1.3 m between adjacent crests. (a) What is the frequency of the waves? Hz (b) Find the period of the wave motion. s

Waves moving on a pond of water are estimated to have a distance of 1.4 m between crests. If they travel at a velocity of 4.2 m/s, calculate the period of the wave motion. Your Answer: Answer

A mass oscillates on a spring, bouncing up and down 20 times per second. From the highest position to the lowest position of the mass is a distance of 8cm.  A) What is the amplitude of the oscillation? B) What is the frequency? C) What is the period of oscillation? D) How many times will the mass oscillate in 12 seconds?

A mass m = 2.8 kg is at the end of a horizontal spring of spring constant k = 490 N/m on a frictionless horizontal surface. The block is pulled, stretching the spring a distance A = 8.5 cm from equilibrium, and released from rest. a) Calculate the period T of the oscillations in seconds.   b)Write an equation for the maximum speed vmax of the block.  c)Write an equation for the maximum acceleration amax of the block.
