Answer:
The mass of the volleyball is 0.32 kg.
Explanation:
Given that,
Initial speed of the ball, u = 4.2 m/s
Final speed of the ball, v = -24 m/s
The impulse delivered to the ball by the player is -9.3 kg-m/s.
To find,
Mass of the volleyball.
Solution,
The change in momentum of the volleyball is equal to the impulse delivered to the ball. It is given by :
m = 0.32 kg
So, the mass of the volleyball is 0.32 kg.
The phenomenon that best illustrates on matter behaving like a wave instead of being a particle is called the interference patterns of electrons. In addition, this phenomenon was described by experimenting that made use of an electron wherein the wave nature of electrons was observed.
Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.
