The answer is A.Yes
Explanation:
The amplitude of a wave is the height of a wave as measured from the highest point of the wave to the lowest on the wave.
-- The area under a velocity/time graph, between two points in time, is the difference in displacement during that period of time.
-- The area under a speed/time graph, between two points in time, is the distance covered during that period of time.
We have that the cricket’s displacement is

From the Question we are told that
Start position 5 meter mark
It jumps to the 10 meter mark.
it jumps back to the 6 meter mark.
Generally the equation for cricket’s displacement. is mathematically given as

Answer:

Explanation:
If m is the mass of the object and v is the velocity of the object. The kinetic energy is due to the motion of an object. It is given by the relation as follows :

The above formula is used to find the kinetic energy of an object.
Answer:

Explanation:
Considering an object that moving about in a circular path, the equation for such centripetal force can be computed as:

The model for the person can be seen in the diagram attached below.
So, along the horizontal axis, the net force that is exerted on the person is:

Dividing both sides by "m"; we have :

Making "v" the subject of the formula: we have:


So, when
= 0; the velocity is maximum
∴




Hence; the maximum walking speed for the person is
