7. What one-dimensional position function must an object have such that the object's position is numerically equal to its speed at all moments in time? In other words if it's at r = 3.0m then it's also traveling v, 3.0m/s at that moment.

Use a scientific calculator to calculate Delta L_fS for D1 = 20 meters and D2 = 40 meters.  I can't believe I have to ask this, but I can't even figure out how to input that in the calculator.

How can I find the graphs, solutions and answers to this problem? (answers should be rounded off to four decimal places)

The answer is incorrect, would there be another way for figuring this out? Thank you.

This was somewhat helpful, but my radius is not 3.5km it's 5km. This is not the answer to my question, it is only similar to it. I can not interpret your handwriting to follow along to answer for my question.

I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.

Two planes take off at the same time from an airport. The first plane is flying at 210 miles per hour on a bearing of S 45.0° E. The second plane is flying in the direction S 45.0°W at 250 miles per hour. If there are no wind currents blowing, how far apart are they after 4 hours? (Round your answer to two decimal places.) mi What is the bearing of the second plane from the first after 4 hours? (Round your answer to one decimal place.) S ° W

In aviation, it is helpful for pilots to know the cloud ceiling, which is the distance between the ground and lowest cloud. The simplest way to measure this is by using a spotlight to shine a beam of light up at the clouds and measuring the angle between the ground and where the beam hits the clouds. If the spotlight on the ground is 0.75 km from the hangar door as shown in the image below, what is the cloud ceiling? 20° 0.75 km
