Answer:2√(2)km Southeast
Explanation:
Displacement=√(2)+√(2)=2√(2)km Southeast
When two waves (either mechanical or electromagnetic) combine in such a way that their peaks and troughs combine to produce a wave of large amplitude, the wave behaviour is known as constructive interference. The opposite process is where the peaks of one wave combines with the troughs of another wave in order to produce a wave of smaller amplitude. This process is known as destructive interference.
Explanation:
Below is an attachment containing the solution.
Answer:
The the average magnitude of the force exerted on the ball by the floor N
Explanation:
Given:
Mass of ball kg
Initial speed
Rebound speed
Contact time interval sec
For finding the average magnitude of the force on the ball by the floor is given by,
Here
N
Therefore, the the average magnitude of the force exerted on the ball by the floor N
