How do you find speed of a ball at maximum height

Physics
1 answer:
Crazy boy [7]3 years ago
5 0

Explanation:

At maximum height, the vertical component of a ball's speed is 0.  So the net speed is equal to whatever the horizontal component of the ball is.  If the ball is launched straight up, the speed at the highest point is simply 0.

Which ball has the greater acceleration at the instant of release
melisa1 [442]
I can't see either of them, so I must assume that they're both
far away from me, at different places in the solar system. 

So I can say with some assurance that whichever ball is on the
more massive planet will have greater acceleration when it's dropped. 
Its acceleration will be constant, from the instant of release until the
instant it hits the "ground" or whatever they call it on that planet.

zubka84 [21]

Answer:The direction the wave travels is parallel to the displacement of the medium.LW.

Electromagnetic waves are an example of this type of wave. TW

Sound waves are an example of this type of wave.LW

Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW

If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW

The direction the wave travels is perpendicular to the displacement of the medium.TW

Explanación:

the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.

In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.
