An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?

Triss [41]

Answer:

$\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}$

Explanation:

Force is equal to mass times acceleration.

$F=m*a$

By dividing both sides by m, we rearrange the formula for a (acceleration).

$\frac{F}{m} =a$

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.

A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².

The mass is 2300 grams, but we need to convert it to kilograms.

To convert grams to kilograms, divide by 1,000
2300 g/1000= 2.3 kg

$F= 6.2 \ kg*m/s^2\\m=2.3 \ kg$

Substitute the values into the formula.

$a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}$

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).

$a=\frac{6.2 \ m/s^2}{2.3 \ }$

$a=2.69565217 \ m/s^2$

Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

$a\approx 2.7 \ m/s^2$

The acceleration is about 2.7 meters per second squared.

A hydraulic system is designed to lift cars for inspection in a service station. The narrow end of the system has a surface area

fiasKO [112]

Given:

Surface area at the narrow end, A1 = 5.00 cm2

Force applied at the narrow end, F1 = 81.0 N

Surface area at the wide end, A2 = 725 cm2

To determine:

Force F2 applied at the wide end

Explanation:

Use the relation

F1/A1 = F2/A2

F2 = F1*A2/A1 = 81.0 N * 725 cm2/5.00 cm2 = 11,745 N

Ans: (b)

The force applied at the wide end = 11,745 N

Explain how changes in temperature affect the particle motion of a substance.

Travka [436]

When the temperature increases, warms, or heats up the molecules become excited. Their movement becomes faster and they tend to move far apart from other molecules.
