A rocket of total mass 3180 kg is traveling in outer space with a velocity of 115 m/s toward the sun. it wishes to alter its course by 30.0°, and can do this by firing its rockets briefly in a direction perpendicular to its original motion. if the rocket gases are expelled at a speed of 1750 m/s, how much mass must be expelled?

    Let Vx = 115m/s

    in order for the angle to be 30 degrees

    tan 30 = Vy/115

    Vy = 66.40 m/s

    Using conservation of momentum:

    m (1750) = (3180 - m) 66.40

    1750m = 211152 - 66.40m

    1750 m + 664.40 = 211152

    1816.40 m = 211152

    m = 211152 / 1816.40

    m = 116.25 kg would be the answer
