neonofarm [45]

Answer:

The attached diagram explains the system,

Sum of Fy = 0

N=9.81

N - mgCos60 = 0

F= ukN= (0.53)(9.81) =

F= 5.12 N

F.d= 1/2(mv.v) - mgdsin60

-5.12*0.5 = 0.5*v^2 - 2*(9.81)*(0.5*sin60)

(a) v = 2.436 m/s

For deflection

-F.x = 1/2(mv.v) - mgxsin60 + 1/2 (k*x*x)

by solving for with values of v, m, g, F, k

800x^2 - 11.87 x - 5.938 = 0

by solving the quadratic equation

x = 0.093, -0.079

(b) x = 0.093 m

correct Answer is 0.093m

If you exert a force on an object in motion you will change its ____.

devlian [24]

If you exert a force on an object in motion, then depending on the
direction of the force you exert and the direction in which it's already
moving, you may speed it up, slow it down, or change the direction
of its motion. Any of these changes is called an acceleration.

In addition to that, you'll change the object's momentum and kinetic energy.
They may increase or decrease ... again depending on the directions of the
motion and the new force.

You will not change the object's mass, inertia, weight, color, cost,
political affiliation, or gender preference.

show mathematically why an 80,000 pound ( 36,000 kg ) big rig taveling 2 mph (0.89 m/s) has the SAME MOMENTUM as a 4,000 pound (

bekas [8.4K]

The momentum value for both Big rig and sport utility vehicle are the same as 16000 pound mph

<u>Explanation:</u>

Given data are as follows

For Big rig, Mass = 80,000 pound (36,000 kg)

velocity = 2 mph (0.89 m/s)

where mph is meter per hour

For sport utility vehicle, Mass = 40,000 pound (1800 kg)

velocity = 40 mph (18 m/s)

The formula to find the Momentum of an object is

Momentum = Mass × Velocity (Kilogram meter per second)

Momentum for Big rig = 80,000 × 2 (pound mph)

= 1,60,000 pound mph

Momentum for sport utility vehicle = 4000 × 40 (pound mph)

= 1,60,000 pound mph

Hence it is mathematically proved that

The momentum of big rig = The momentum of sport utility vehicle

1,60,000 pound mph = 1,60,000 pound mph

What is thermal expansion and how does it relate to heat?

kiruha [24]

Answer:

"The idea behind thermal expansion is that gases expand as the temperature increases. If you have a balloon and you heat up the contents, the balloon will get larger. Scientists use the term ideal gas law to describe this activity. Liquids expand and contract, too, but there is a lot less change than in gases."

I don't know if this is what u meant, but, hope this helps :3
