Final speed after collision with the wall
before collision the speed of ball initially
time taken for the collision
now as per the formula of acceleration we know that
now plug in all values in it
so acceleration is - 5 m/s/s for above situation
Answer:
Normal Force is usually perpendicular to the movement and static friction usually means that there is no movement.
Explanation:
The work donde by any force on an object is equal to the displacement of the object multiplied by the component of the force that is in the direction of the displacement.
Normal force is usually perpendicular to the movement, so there is no component in the direction of the displacement. This is why it is zero in most circumstances.
<em>Static</em> friction on the other hand, usually means that there is no movement at all (it's static). It means that there is no displacement between the object and ground (in most cases). If there is no displacement, there is no work.
in the same direction as the wave
Explanation:
In a compression wave, the particles in the medium moves in the same direction as the wave source.
A wave is generally defined as a disturbance that transmits energy.
- There are two types of waves based on the direction through which they are propagated.
- Transverse waves are directed perpendicularly in the direction of propagation.
- Examples are electromagnetic waves.
- Longitudinal waves are parallel to their source. Examples are sound waves, p-waves.
- They are made up of series of rarefaction and compression.
