A ball of m1 is held slightly above ball of mass m2. The two balls are droped simultaneously, falling distance h vertically from rest. Air resistance is negligible. The second ball collides with the floor, then with the first ball. All collisions have coefficient of restitution r. After the second collision, the second ball momentarily stops dead.
a. Calculate the mass ratio m1/m2.
b. Calculate the height to which the first ball rebounds. Treat the diameters of the balls themselves as neglibible.
What amplitude of simple harmonic motion of the spring-blocks system puts the smaller block on the verge of slipping over the larger block.
A certain loudspeaker has a diameter of 45 cm. At what frequency would the wavelength of sound it emits in air be equal to its diameter.
