5 examples of how intertia is used in real life

Mariulka [41]

Answer:

- your body moving forwards when sudden brakes/force is applied e.g. sudden braking in a car

- feeling a backwards force when something moves quickly from rest e.g a bus

- when you stir a cup of tea, it continues to swirl for a short period of time even though you have stopped

- when shaking a tree, it's leaves or fruit fall down

- satellites which move due to the inertia of motion

hope this helped :)

Which of the following is a correct step in the process of adding 8.0 x 10^ -2 and 6.0 x 10^ -3

dybincka [34]

Explanation:

In order to compute correctly the sum of the two terms, we have to rewrite one of them such that they have the same exponent.

The two terms are:

$8.0 \cdot 10^{-2}$

$6.0 \cdot 10^{-3}$

For instance, we can re-write the second term such as it also has a power $10^{-2}$ . In order to do that, we have to move the decimal point one place to the left, therefore:

$6.0 \cdot 10^{-3} = 0.6\cdot 10^{-2}$

At this point, the two numbers have the same exponent, so we can just add them together by adding the bases and keeping the same exponent, -2:

$8.0\cdot 10^{-2} + 0.6 \cdot 10^{-2} = (8.0 + 0.6) \cdot 10^{-2} = 8.6\cdot 10^{-2}$

If a 15kg mass weighs 372 N on Jupiter, what is Jupiter's gravitational acceleration?

Dimas [21]

Answer:

Jupiter's gravitational acceleration is 24.8 m/s^2

Explanation:

Recall that the weight under the influence of a gravitational acceleration G is defined as:

Weight = m * G

Then, in our case we have

372 N = 15 kg * G

G = 372/15 m/s^2

G = 24.8 m/s^2

A man cleaning his apartment pushes a vacuum cleaner with a force of magnitude 84.5 N. The force makes an angle of 33.9 ◦ with t

Sav [38]

Answer:

183.75641 Joules

Explanation:

F = Force of the vacuum cleaner = 84.5 N

s = Displacement of the vacuum cleaner = 2.62 m

$\theta$ = Angle the force makes with the horizontal = 33.9°

Work done is given by

$W=F\times scos\theta\\\Rightarrow W=84.5\times 2.62\times cos33.9\\\Rightarrow W=183.75641\ J$

The work done by the force of the vacuum cleaner is 183.75641 Joules
