Answer:
0.16 kgm/s
Explanation:
= Mass of pellet = 2 g
= Mass of golf ball = 45 g
= Initial Velocity of pellet = 60 m/s
= Initial Velocity of golf ball = 0 m/s
= Final Velocity of pellet = 40 m/s
= Final Velocity of golf ball
In this system the linear momentum is conserved

As the golf ball is being shot 4 times every second the momentum delivered to the golf ball each second is 
If you use the stairs at normal speed, you will survive longer, and go up higher.
When going up the stairs twice as fast, you lose energy more quickly, but height would remain the same.
Our solar system consists of the sun and the 9 planets and their moons.
The galaxy is outside our solar system.
Kinetic energy is formed when the object is in motion.
Potential energy is the energy that is formed relative to others.
One of the example is Corn flour factory.
Corn turned into flour by a windmill that moved by the waterfall. Movement of the mill is relative to the power given by waterfall (potential energy) and the spinning crushes the corn into flour (kinetic energy)
