Challenge Problem (Extra Credit) A car with bad shocks has a mass of 1500 kg. Before you go for a drive with three of your frien
Nastasia [14]

Answer:

167.354 m

Explanation:

We are given;

The mass of the car with bad shock;

m = 1500 kg

The distance at which the car sinks; x =

6 cm = 6 × 10^(−2) m

The total mass of 4 people; m_t = 11 kg

The total speed in the highway; V = 65

mph = 29.058 m/s

The spring's constant can be calculated from the formula;

F = Kx

F is also equal to mg.

Thus;

m_t × g = Kx

K = (m_t × g)/x

K = (11 × 9.81)/(6 × 10^(−2))

K = 1798.5 N/m

Mass of car and four people;m_(c+t) = 1500 + 11 = 1511 kg

Thus, the period cam be calculated from the formula;

T = 2π√((m_c+t)/k)

T = 2π√(1511/1798.5)

T = 5.759 s

the distance between adjacent bumps is calculated from;

Velocity = distance/time

Distance = velocity x time

Distance = 29.058 × 5.759

Distance = 167.354 m

3. The function of the _______ is to convert the up-and-down motion of the piston into rotary motion that can be used to power t
DENIUS [597]
The function of the crankshaft is to convert the up-and-dwon motion of the piston into rotary motion that can be used to power the vehicle.

I attache an image of a crankshaft.

The pistons are connected to the crank pins ans when the pistons move up an down the crankshaft rotate, and so the recoprating movement of the pistons is converted into rotary motion.

A 45-gram object that has a volume of 9 mL has a density of
yanalaym [24]

Answer:

<h2>  The answer is </h2><h2>a. 5g/mL</h2>

Explanation:

Given data

mass m= 45g

volume v= 9mL

we know that density=m/v

substituting our given data we have

density=\frac{45}{9} =5g/mL

What is Density?

The Density of a body can be defined as the ratio of mass to volume,

or

Density, mass of a unit volume of a material substance. The formula for density is Density= \frac{mass}{volume},

where d is density,

M is mass, and

V is volume.

Density is commonly expressed in units of grams per cubic centimetre.
