Non renewable resources are resources that we can only use for so long until they’re gone and they can not be brought back. So like coal would be a non renewable resource. Renewable resources are resources that we can continue to use and we will always have them. An example of a renewable resource would be oxygen. We can breathe as much oxygen as we want but we will never run out of it.

With the same block-spring system from above, imagine doubling the displacement of the block to start the motion. By what factor

Fofino [41]

Answer:

A) K / K₀ = 4 b) v / v₀ = 4

Explanation:

A) For this exercise we can use the conservation of mechanical energy

in the problem it indicates that the displacement was doubled (x = 2xo)

starting point. At the position of maximum displacement

Em₀ = Ke = ½ k (2x₀)²

final point. In the equilibrium position

$Em_{f}$ = K = ½ m v²

Em₀ = Em_{f}

½ k 4 x₀² = K

(½ K x₀²) = K₀

K = 4 K₀

K / K₀ = 4

B) the speed value

½ k 4 x₀² = ½ m v²

v = 4 (k / m) x₀

if we call

v₀ = k / m x₀

v = 4 v₀

v / v₀ = 4

Spiderman, whose mass is 74.0 kg, is dangling on the free end of a 11.0-m-long rope, the other end of which is fixed to a tree l

Anestetic [448]

Answer:

W = -1844.513 J

Explanation:

GIVEN DATA:

mass of spider man is m 74 kg

vertical displacement if spider is 11 m

final displacement = 11 cos 60.6 = - 6.753 m

change in displacement is = -6.753 - (-11) = 4.25 m

gravity force act on spiderman is f = mg = 74 × 9.8 = 725.2 N

work done by gravity is $W = F \delta r cos\theta$

$W = 725.2 \times 4.25 \times cos 180$

where 180 is the angle between spiderman weight and displacement

W = -1844.513 J

Travels 11,000 feet along a dark desert highway if the car averages 84 mph find the amount of time to cover this distance

laila [671]

The time taken by traveler to cover the distance is,

$t=\frac{d}{v}$

Substitute the known values,

$\begin{gathered} t=\frac{(11000\text{ ft)}}{(84\text{ mph)(}\frac{1.46667\text{ ft/s}}{1\text{ mph}})_{}} \\ \approx89.3\text{ s} \end{gathered}$

Therefore, the time taken by traveler to cover the distance is 89.3 s.
