A ball is dropped from 215m. How long will it take to reach the ground? Use 9.8
1 answer:
Answer:
The time is
Explanation:
From the question we are told that
The height of the platform where the ball was dropped from is s = 215 m
The acceleration due to gravity is
Generally from kinematic equations
Here u is the initial velocity of the ball and the value is u = 0 m/s given that the ball was at rest before it was dropped
So

Path difference between the waves is given by
for destructive interference m=0 I.e.
frequency is given by
where
For next frequency which will cause destructive interference is

Frequency corresponding to this wavelength
As we know that total work done by a force is given by
so it is product of force and displacement along same direction
as we can write it as
so it must be the product of force and displacement in same directions so correct answer must be
<u>B. in the same direction as the displacement vector and the motion.</u>
