Answer:a)45cos40 b)45sin40 c) 2.95 d)102
Explanation:
a) 
b) 
c) Since air resistance is negligible, the only force acting on the golf ball is gravity. Thus, its vertical acceleration is -<em>g</em>. We know the final velocity must be 0 m/s, because this will be when the golf ball reaches the maximum height and starts to change direction (it falls back to the ground). We also know initial velocity in the vertical direction (see part b). Thus, we can use this equation: 
.
d) The horizontal distance traveled is dependent on (1) how long the ball is in the air and (2) what the horizontal velocity is. (1) was found in part c, and (2) was found in part a.
Answer: D. The object would have an acceleration of 6 m/s/s to the right.

PWC stands for Personal WaterCraft.
When you modify a PWC's exhaust system it may raise noise to an illegal level.
<span>That's why, you should avoid maneuvers that cause the engine exhaust to lift out of the water. </span>The noise can be irritant to people, so avoid making excessive noise near residential and camping areas.

The magnitude and direction (inward or outward) of the net flux through the cell boundary is - 0.887 wb.m².
<h3>
What is flux?</h3>
Flux describes any effect that appears to pass or travel through a surface or substance.
The magnitude and direction (inward or outward) of the net flux through the cell boundary is calculated as follows;
Ф = Q/ε
where;
- Q is net charge
- ε is permittivity of free space
Φ = (-7.85 x 10⁻¹²)/(8.85 x 10⁻¹²)
Φ = - 0.887 wb.m²
