The ball is hit with an initial vertical velocity of

(147 m/s) sin(38º) ≈ 90.5 m/s

Recall that

<em>v </em>² - <em>u </em>² = 2 <em>a</em> ∆<em>y</em>

where <em>u</em> and <em>v</em> are initial and final velocities, respectively; <em>a</em> is acceleration; and ∆<em>y</em> is displacement.

Vertically, the ball is in freefall, so it is only subject to acceleration due to gravity, with magnitude <em>g</em> = 9.80 m/s² in the downward direction. At its maximum height, the ball has zero vertical velocity (<em>v</em> = 0) and the displacement is equal to the maximum height, so

0² - (90.5 m/s)² = 2 (-<em>g</em>) ∆<em>y</em>

∆<em>y</em> = (90.5 m/s)² / (2<em>g</em>)

∆<em>y</em> ≈ 418 m

Diverging lens

Explanation:

Given parameters:

Power of lens  = -2.0D

Unknown:

Focal length  = ?

Solution:

The power of lens is the reciprocal of the focal length;

   P  = \frac{1}{f}

where  f is the focal length

 f  = \frac{1}{P}   = -\frac{1}{2}

The lens is a diverging lens

Light travels from the sun to the earth, a distance of 144,000,000,000 meters, in 480 seconds. Calculate the approximate velocit
mel-nik [20]

Answer:

The answer is C.) 300,000,000 m/s

Explanation:

Light travels at a constant rate of 300,000,000 m/s. this can be determined by dividing the distance (144,000,000,000 meters) by the time (480 seconds). that's pretty fast. in fact, nothing can travel any faster than this. ever.

S_A_V [24]

Answer:

There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its

Sauron [17]
Hi,

The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
