Earth orbits Sun
a
Earth orbits Sun in circular path with the same speed because its total angular momentum is unchanged
b
Earth orbits Sun in elliptical path at faster speed when it's near the Sun because its total angular momentum changes
c
Earth orbit Sun in elliptical path at slower speed when it's near the Sun because its total angular momentum is unchanged
d
Earth orbits Sun in elliptical path at faster speed when it's far from the Sun because its total angular momentum is unchanged
e
Earth orbits Sun in elliptical path with same speed because its total angular momentum is unchanged
f
Earth orbits Sun in elliptical path at slower speed when it's far from the Sun because its total angular momentum is unchanged

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
