Use the mass and radius of the earth as given in section 7.4 to calculate
how much faster a clock in Denver runs than does a clock in Washington,
D.C. Denver is 1600m higher than Washington, D.C.

Class Work A bullet is shot into a wooden block suspended by strings and lodges in the block, losing energy in its penetration, and the increase in the height of the swinging block and bullet is measured. If the masses of the bullet and block are 19 gram and 50 gram respectively, and the swing rises 0.1m, determine the velocity of the penetrating bullet and the fraction of its energy lost during the penetration.

A mass of 5 kg is first weighed on a balance at the top of a tower 20 m high. The mass suspended from a fine wire 20 m long and reweighed. Find the difference in weight.

The two straight oscillators are 1.5 and 5 m in length. How long after that they will move in opposite positions?

Find the positions at which a particle of mass m move on the x-axis with energy v=E/q^4(x^4+4ax^3-8a^2x^2) is in stable equilibrium

The earth falls freely in a gravitational field that is largely due to the
moon7
. Moreover, the earth is surrounded by a sphere of liquid called the
ocean. Based on your answers to problem 1, do you expect the ocean to
be perfectly round? Draw a picture of its shape.

The spactime diagram below is drawn in the reference frame of a small lab sitting on the earth (which experience a newtonian gravitational field of g=10m/s^2 ) which of the worldline shown below has the greatest proper time? Why the answer you choose is correct
