Kinetic energy because it's moving
(6) Given that,
Force in east direction = 67 N
Force in west direction = 82 N
Solution,
According to the given figure,
Two forces are acting in opposite direction. Maximum force is acting in west direction. It means the net force is acting in west direction.
Net force = 82-67
= 15 N (Due west)
The forces are unbalanced. It is because the magnitude of force in west is more than in east.
Net force = 15 N, Direction of motion = West and the forces are unbalanced.
The point In the motion that the balls will be closest to each other is as at the time as the second ball is thrown or lunched.
<h3>Will the first ball always be travelling faster than the second ball?</h3>
No, The two motions are said to be parallel to one another, so they that they both the same timing. Hence, the time it takes for both balls to be able to fall to the ground is said to be the same.
Yes, the both balls have the same speed because of two balls are said to hit the ground, they are said to be done at the same height as well as the same energy and so they have the same speed.
Note that balls will take about 2 seconds to be able to hit the ground.
The horizontal projection velocity of the second ball can be changed so that the balls arrive at the ground at the same time and so the balls will be closest to one another if the second ball is thrown.

Answer:
A pipe has a length of 1.15 m.
a) Determine the frequency of the first harmonic if the pipe is open at each end. The velocity of sound in air is 343 m/s. Answer in units of Hz
b) What is the frequency of the first harmonic if the pipe is closed at one end?
Answer in units of Hz
Explanation:
I added individual steps for clarity. Note that g must be positive if the solution is to be real.
