One end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates at a frequency 125Hz. The other end passes over a pulley and supports a mass of 1.40kg . The linear mass density of the rope is 5.00×10?2kg/m.
a) What is the speed of a transverse wave on the rope?
b) What is the wavelength?
A 4.20kg steel ball strikes a wall with a speed of 7 m/s at an angle of 60° with the surface. It bounces off with the similar speed and angle. If the ball is in contact with the wall for 0.20 s, what is the average force exerted by the wall on bal..
