Answer: average speed of the ball would be 48 mph
Explanation:
because all you have to do is multiply 24 x .5 and that gives you your answer
Maybe The 3rd One Not Sure!
How dense the medium is in the compression part of the wave and how rare the medium is in the rarefaction part of the wave is a measure of the longitudinal wave's amplitude.
By definition, average acceleration will be:
a=(v(f)-v(i))/t
a=(2-14)/6=-2 (m/s^2)
________
-2(m/s^2)
Explanation:
The force is 186.5 N. 3.8% of the force is directed downward. So the vertical component of the force is:
Fᵧ = 0.038 (186.5 N)
Fᵧ = 7.087 N
The horizontal component is found with Pythagorean theorem:
F² = Fₓ² + Fᵧ²
(186.5 N)² = Fₓ² + (7.087 N)²
Fₓ = 186.4 N
So the work done is:
W = Fd
W = (186.4 N) (7.4 m)
W = 1379 J
Round as needed.
