How to convert momentum into speed?

1 answer:

6 0

In a collision an object experiences a force for a specific amount of time, which results in a change momentum(the objects mass may ethier speed up or slow down). Impulse will be produced because of force appiled to an object over a period of time.

I am really struggling with this question because I can't find anything on aphelion and perihelion, it's not a topic we went ove

Hoochie [10]

I have a strange hunch that there's some more material or previous work
that goes along with this question, which you haven't included here.

I can't easily find the dates of Mercury's extremes, but here's some of the
other data you're looking for:

Distance at Aphelion (point in it's orbit that's farthest from the sun):
69,816,900 km
0. 466 697 AU

 Distance at Perihelion (point in it's orbit that's closest to the sun):
46,001,200 km
0.307 499 AU 

Perihelion and aphelion are always directly opposite each other in
the orbit, so the time between them is 1/2 of the orbital period.

Mercury's Orbital period = 87.9691 Earth days

1/2 (50%) of that is 43.9845 Earth days

The average of the aphelion and perihelion distances is

1/2 ( 69,816,900 + 46,001,200 ) = 57,909,050 km
or
1/2 ( 0.466697 + 0.307499) = 0.387 098 AU

This also happens to be 1/2 of the major axis of the elliptical orbit.

If you are driving 100 km/h along a straight road and you look to the side for 1.6 s , how far do you travel during this inatten

denis23 [38]

Answer:

The distance traveled is 44.45 m

Solution:

As per the question:

Average speed, $\bar{v} = 100\ km/h$

Time, t = 1.6 s

Now, convert the average speed into m/s:

1 km = 1000 m

1 h = $60\times 60 = 3600\ s$

To calculate the distance traveled:

Now,

$100\ km/h = \frac{100\times 1000}{3600} = 27.78\ m/s$

We know that:

Speed, $\bar{v} = \frac{distance,\ d}{time,\ t}$

Thus

$d = \bar{v}t$

$d = 27.78\times 1.6 = 44.45\ m$

A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of mc001-1. Jpg 6. 67

Andrei [34K]

The approximate length of the arc intersected by the central angle is 20.94 inches.

The given parameters:

Radius of the circle, r = 10 inches
Central angle, $\theta = \frac{2\pi }{3} \ rad$

The approximate length of the arc intersected by the central angle is calculated as follows;

S = rθ

where;

S is the length of the arc

Substitute the given parameters and solve for the length of the arc

$S = 10 \ in \times \frac{2\pi }{3} \\\\S = 20.94 \ inches$

Thus, the approximate length of the arc intersected by the central angle is 20.94 inches.

What is your average speed for your walk

dimulka [17.4K]

My average speed for a walk depends on how far I walk.
If I walk one mile or more, then my average speed is about 2 miles per hour.
