1) The distance between the sun and earth is 1.5 x 1011 m and the earths orbital speed is 3x104m/s . Use this information to calculate the mass of the Sun. (G = 6.67 x 10-11 N m2/kg2).
2. If a disk is rotating at 1200 rev/min what is the angular velocity in rad/sec, what angular (dece)acceleration is required to stop it in 3 min. What torque will do this? Assume the mass of the disk is 3kg and radius 20cm.
3. A high powered rifle of mass 5kg fires a 15-g bullet with a muzzle velocity of 3 x 10 4 cm/sec. What is the recoil velocity of the rifle? (Hint use momentum conservation before and after firing).

The maximum distance from the Earth to the Sun (at aphelion) is
1.521 1011 m, and the distance of closest approach (at perihelion)
is 1.471 1011 m. The Earth's orbital speed at perihelion is 3.027
104 m/s. Ignore the effect of the Moon and other planets. (a)

The Venus-Sun distance is 108 million kilometers, and the
Earth-Sun distance is 150 million kilometers. Suppose an imaginary
line from Venus to the Sun forms a right angle with an imaginary
line from Earth to the Sun. How long would it take light to travel
from the Sun to a spaceship halfway along the straight-line path
between Venus and Earth? The time is in minutes.
