Answer:30.34 m
Explanation:
Given
launch angle
Initial velocity u=31.9 m/s
Position of net = 39.1 m
We know equation of trajectory of a projectile is
Therefore Net should be placed 30.34 m above ground
The given statement "A ball is moving upwards and to the left. The net forces acting on it are also upwards and to the left" does not provide enough information.
Answer: Option C
<u>Explanation:</u>
Consider an object thrown at some angle to the left. Then, we can observe that the body moves both upwards and towards left. The reason is why, the resultant force acts towards the direction. If we solve the force into two components, through the given angle, then, we get the forces acting in two different directions.
When you push something, you apply a force. Except this, you still may not be able to change its acceleration. That is because there might be another force that nets against yours. So, the body moves upward and towards the left only if it has net forces acting in both the directions. Hence, concludes that given phrase does not give enough details.
