5) The velocity of light is 3x108m/s. How long does it take a
reach the earth from the sun, which is 1.5x10 m away?
The radius of the moon is (3.65) of the radius of the earth
the acceleration due to gravity of the moon is of that one
earth's surface. Calculate the mass of the moon. (Ans
7.46x1022kg)
Calculate the escape velocity of a satellite from the earth's surface
(G = 6.7x10-11Nm?kg-?, mass of the earth = 6x1024kg and i the
earth's radius = 6.4x10ºm)

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
