(a) (5%) if the surface is frictionless and

(b) (3%) if the surface is not frictionless and the block moves a distance d₂ before it stops. (Assume that the kinetic friction force between the surface and the block is the same as that between the bullet and the block.)

(a) (4%) Kepler's second law and

(b) (4%) Kepler's third law for a circular orbit of radius r and period T.

(c) (4%) If the gravitational force between masses M and m were G'Mm/r³, with G' the proportional constant and r the distance between two masses, how would the Kepler's second and third laws be modified?

(a) (4%) What is the torque of the gravitational force on the axis at O at the angleθ shown in the Figure?

(b) (5%) What is the period of the oscillation?

(a) (4%) If the energy added to the gas by heat through path ABC is +188 J, what is the work done on the gas from A to B?

(b) (4%) If the pressure at A is 32 times that of C, what is the energy exchanged with the surroundings by heat as the gas goes along path CDA?

(c) (4%) If 67 J is added to the gas by heat as it goes from D to C, what is the change in internal energy in going from D to A?

(d) (4%) Suppose the molar specific heat at constant volume of the gas is C_v = 3R/2, with the gas constant R. If the dashed path from A to C is an adiabatic process, what is the ratio V_C/V_Dbetween the volume V_c at C and V_Dat D? (Note: are horizontal
