A ball of mass 100g thrown by a man moves at a velocity of 100m/s. what is the momentum? need the answer step by step plssss!! i need it fast!!!!!!!
Explanation:
Mass of the ball= 100 g = 0.1 kg
Velocity of the ball before collision=10 m/s
Momentum of the ball before collision, p(i)=mv= 0.1×10=1 kgm/s
Since, ball returns back with same velocity
Therefore, velocity of ball after collision = -10 m/s (-ve sign due to opposite direction)
So, momentum of ball after collision,p(f) = 0.1 ×(-10) = -1 kgm/s
Now, Impulse generated in the ball= change in momentum= p(f)-p(i)= -1–1= -2 kgm/s
the movement of liquid particles through a circular motion
Answer:
Solids - vibrational (and rotational); moving very slowly.
Liquids - vibrational, rotational, and translational; moving quickly.
Gases - vibrational, rotational, and translational; moving very quickly.
Explanation:
Particles are always moving. No matter what. There is a certain point where they move so slowly it is considered minuscule, but they are in fact moving.
Thus, in solids, liquids, and gases, you can expect particles to move in a certain trend. That trend is average kinetic energy of the particles and the forces holding them together (attraction).
