Answer: 19.97 m≈20m

Explanation:

Ep=mGh

9800J=50*9.81*h

h=9800/490.5

h=19.97 m

Calculate the force of gravity on the 0.50-kg mass if it were 6.4×106 m above earth's surface (that is, if it were two earth rad
Sunny_sXe [5.5K]

Radius of Earth is given as

R = 6.4 * 10^6 m

now here the height from the surface of earth is same as that of radius

h = 6.4 * 10^6 m

now here the acceleration due to gravity at this height is given as

g' = \frac{GM}{(R+h)^2}

g' = \frac{GM}{4R^2}

g' = \frac{g}{4}

now the force of gravity on the given object will be

F = mg'

F = m*\frac{g}{4}

F = 0.5 * \frac{9.8}{4}

F = 1.225 N

<em>so the force of gravity on it is 1.225 N</em>

A stone is dropped from the upper observation deck of a tower, 900 m above the ground. (assume g = 9.8 m/s2.) (a) find the dista
aleksley [76]
The original vertical velocity = 0 (because the stone was dropped).
Assume that air resistance may be ignored.

Let x = the distance the stone drops in time t.
Then
x = 0*t + (1/2)*(9.8 m/s²)*(t s)²
   = 4.9t² m

The height of the stone above ground is
h(t) = 900 - 4.9t² m

Answer: h(t) = 900 - 4.9t²

Releasing the clutch pedal reapplies the clamping force and reconnects the engine and transmission by firmly clamping the clutch
Luden [163]

Answer:

Preassure plate

Explanation:

The flywheel, clutch disc, pressure plate, throw-out bearing clutch fork, and the pilot bearing are the components of a clutch. It works when the flywheel bolts onto the crankshaft and therefore the <em>pressure plate bolts back into the flywheel.</em>

I hope you find this information useful and interesting! Good luck!
