Answer:
"Cannot be determined," if that's an answer choice. It depends on the velocities of both objects, since momentum=mass*velocity.
Explanation:
Answer:
mass of the ball will be 1 kg
Explanation:
We have given force F = 0.5 N
This force must be equal to the centripetal force for the ball to revolve in the circle
So
Centripetal acceleration is given as
We have to calculate the mass of the ball
We know that force is given by
So
m = 1 kg
So mass of the ball will be 1 kg
Difference is between the freezing point of water and the boiling point of water.
Answer:
1.
2.
Explanation:
Given:
- mass of block,
- spring constant,
- maximum velocity of block,
1.
<u>We know from the energy of oscillating spring:</u>
2.
Now, given that:
instantaneous position,
we find angular speed,
So we have
Answer:40.19 N
Explanation:
Given
Force needed to hold the ball at
From FBD we can write
For
for
Force is
Divide 1 and 2 we get
