Please help me with questions 1, 2, 3, 4, and 5
1. A paintball with a mass of 0.15 kg is fired from a paintball gun that has a
mass of 5.5 kg. The paintball leaves the gun with a velocity of 45 m/s [N]
having accelerated for 0.10 s. Calculate the acceleration and the final
velocity of the paintball gun.
2. A diver with a weight of 833 N dives from a boat with a mass of 375 kg. If he
leaves the boat with a velocity of 2.25 m/s [W] after accelerating for 0.50 s,
what will be the final velocity of the boat?
3. A car having a mass of 999 kg is travelling with a velocity of 26 m/s [NJ. It
then changes its velocity to 28 m/s [N]. If this change took 2.5 s, find the
unbalanced force needed to cause this acceleration.
4. Two hockey players standing stationary on the ice facing one another. Player
A has a mass of 85 kg and Player B is 110 kg. They shove each other and
Player A ends up with a velocity of 1.5 m/s [W]. Find the final velocity of
Player B.
5. While driving down the road, Anna Litical observed a bug
striking the windshield of her car. Quite obviously, a case
of Newton's third law of motion. The bug hit the
windshield and the windshield hit the bug. Which of the
two forces is greater: the force on the bug or the force on the
windshield?
