The formula v equals the square root of the quantity 64 multiplied by h end of quantity gives the velocity v in feet per second
NemiM [27]
The equation is derived from the conservation of energy, specifically from potential energy stored at a given height in a gravitational field.

When potential energy is completely converted to kinetic energy you have:

(mv^2)/2=mgh  divide both sides by the mass m

v^2/2=gh  multiply both sides by 2

v^2=2gh take the square root of both sides

v=√(2gh)  and working with imperial units for acceleration due to gravity, g=-32ft/s^2

v=√(-64h)  but the change of h as it falls is negative h so

v=-√(64h) so if an object falls from a height of 88ft we have:

v=-√(64*84)

v=-√5376

v≈-73.32 ft/sec (to the nearest hundredth of a foot per second)

Note that this is the velocity, it is negative 73.32 ft/sec.

The question inadvertently asked for velocity and provided answers for SPEED.  Velocity is a vector and has both magnitude and direction, whereas speed just has magnitude.

So its final speed is 73.32 ft/sec

So if they actually wanted velocity none of their answers is correct :P

Timed 5 minutes Please How do I solve this? I'm confused Find the value of sin x° and cos y°
jasenka [17]
Po ^2 = 6^2 + 8^2
Po^2 = 36 + 64 = 100
So Po = 10
Sin x = 8/po = 8/10= 0.8
Cos y = 6/po = 6/10=0.6

Please please please help quick
fredd [130]

Answer:

3\sqrt{5}

Step-by-step explanation:

Since the triangle has a right angle, we are going to use pythaogoran theoem, which is a^{2} +b^{2} =c^{2}, where a and b are the legs and and c is the hypotunese/ slated side.  Let set it up.

3^{2} +6^{2} =c^{2}

9+36=c^2

45=c^2

\sqrt{45}=

Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical

The perfect square root is 9 because 9 goes into 45 5 times.

\sqrt{9x5}

Then take the sqr root of 9 and we have 3\sqrt{5}
