The net force on an object that is accelerating at a rate of 4 m/sec is 255 N. What is the mass of the object in kg?
aleksklad [387]

Answer:

Given - acc = 4 m/ s^2

Force = 255 N

To find = mass

Solution -

Using the formula,

f = m \times a

Particle model to predict what will happen if a sharp object creates a hole in the soccer ball
malfutka [58]

Complete Question:

A soccer player pumps air into a soccer ball until no more air can be pushed inside.Use the particle model to predict what will happen if a sharp object creates a hole in the soccer ball.

Answer:

particles will rush out of the ball until the pressure is equal inside and outside the ball

Explanation:

We need to understand  when a ball is  pumped with air until no more air can be pushed inside, that  the particles inside the ball are closer together and bounce into each other more than the particles outside the ball  and this makes the pressure inside the ball greater than that outside.

Now when a sharp object creates a hole in the soccer ball the particle move from a place of high pressure to a place of lower pressure because the  force at the place of high pressure overpowers the force at the place of lower pressure.
