Use bisection to determine the drag coefficient needed so that a 65kg bungee jumper has a velocity of 35m/s after 4.5s of free f

all. Note: The acceleration of gravity is 9.81m/s2. Start with initial guesses of xl= 0.2 and xu= 0.3 and iterate until the approximate relative error falls below 2%.

A NASA explorer spacecraft with a mass of 1,000 kg takes off in a positive direction from a stationary asteroid. If the velocity
Jet001 [13]

Before the launch, the momentum of the (spacecraft + asteroid) was zero.  So after the launch, the momentum of the (spacecraft + asteroid) has to be zero.

Momentum = (mass) x (velocity)

Momentum after the launch:

Spacecraft:  (1,000 kg) x (250 m/s) = 250,000 kg-m/s

Asteroid: (mass) x (-25 m/s)

Their sum:  250,000 - 25(mass) .

Their sum must be zero, so  250,000 kg-m/s = (25 m/s) x (mass)

Divide each side by  25 :  10,000 kg-m/s = (1 m/s) x (mass)

Divide each side by (1 m/s) :  10,000 kg = mass

Answer:

56.7 m³

Explanation:

The radius of the circular area covered by the spill is 4.25 km

You can find the area covered by the spill by applying the formula for area of a circular surface

A=π×r² where π=3.14 and r=4.25km

A= 3.14×4.25² = 56.72 km²

Remember the total area is on average at 1 micron (1μm) thick.This is to say

1μm=1m³

So the minimum volume of oil covering the ocean surface in meters will be;

Change km² to m²

56.72 km²= 56.72×1000000=5.67×10⁷ m²

Finding the volume;

Volume = Area * thickness

Volume= 5.67×10⁷ m² * 1× 10⁻⁶ = 56.7 m³

Minimum amount of oil that was spilled is 56.7 m³

A hydraulic system contains 3 pistons. The input piston has an area of 0.625 in2, one of the output pistons ( piston A ) has an
Xelga [282]

The area of Piston A is 13.88 in^2

What is a hydraulic system?

The hydraulic system functions by using pressurized fluid.  The power of liquid fuel in hydraulics is significant and as a result, they are commonly used in heavy equipment.

Hydraulic system simply means a mechanical function that operates through the force of liquid pressure.

Here

A hydraulic system contains 3 pistons.

Pressure, P = 1440 psi

for piston A:

Area, A= 0.625 in^2

Force, F = 20,000 lb

We know that,

Force = Pressure x Area

F = P x A

Area ( piston A) = F / P

A = 20,000 / 1440

A = 13.88 in^2

Hence,

The area of Piston A is 13.88 in^2
