Answer:
0m/s
Explanation:
Since its fired at an angle, at the top there will be a split second where the velocity will be 0, as it has a parabolic shape, so the speed at the top of its path is 0
Answer:
When a candle was blown out, the flame stops immediately but the wick and the wax are both still hot, so pyrolysis continues for a few seconds. Explanation:
Answer:
Kinetic energy does not stay the same at all heights
Explanation:
Well as the height and wind increase so does the kinetic energy it's like when you fall as you are about to hit the floor you speed increases
HOPE THIS HELPS YA :)
<u>Answer</u>
B•Horizontal=11.49 m/s
Vertical=9.64 m/s
Using the concept of a trigonometric ratios,
sin θ = y/hypotenuse
where y is the vertical component.
sin 40 = y/15
y = 15 × sin 40
= 9.64 m/s
vertical component = 9.64 m/s
cos θ = x/hypotenuse
where x is the horizontal component
cos 40 = x/15
x = 15 × cos 15
=11.49
Horizontal component = 11.49 m/s
