The planet Mars has a mass of 6.417×1023 kg. The small moon Phobos orbits Mars in a near circular orbit at an orbital distance (from the centre of Mars to the centre of Phobos) of 9,376km. Phobos has a mass of 1.066×1016 kg and a mean radius of 11.27 km. As an approximation you may assume the moon is spherical. It is in a tidally locked orbit so that the same side of Phobos faces Mars all the time.

Calculate the angular velocity w of Phobos.
Suppose there is some loose material on the surface of Phobos facing Mars. Write an
expression for the total gravitational force acting on the material.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
