When estimating distances from a table of velocity data, it is not necessary that the time intervals are equally spaced. After a space ship is launched, the following velocity data is obtained. Use these data to estimate the height above the Earth's surface at 124 seconds. t (sec) v (ft/s) 11 242 17 374 21 462 44 968 60 1320 63 1461 124 4328 lower estimate of distance traveled = miles upper estimate of distance traveled = miles

a) What is the average speed in kilometers per second of the Earth around the sun, given that the radius of the Earth's orbit is 1.5×108km?   b) What is the average velocity of the Earth over a year's time?

the earth is approximately 1.5x10^8 km from the sun. how many minutes does it take light to travel from the sun to the earth? light travels at a speed of 3.00 x10^10 m/s

A space probe on the surface of Mars sends a radio signal back to the earth, a distance of 7.37 x 10^7 km. Radio waves travel at the speed of light (3.00 x 10^8 m/s). How many seconds does it take for the signal to reach the earth

An object was observed to have velocity v1 in m/s at time t1 seconds and later velocity v2 in m/s at time t2 seconds: v1=0; t1=0.6; v2=14; t2=4.0 Units are m/s and s. Find the average acceleration of the object in m/s/s. Please include 3 sig. figs. in your answer.

how many kilometers will you travel in a span of 2.5 h if you are going at a speed of 5.0m/s?  (please solve accurate and fast and it should not be hand written) it must be typed THANK YOU!

If an average-size man jumps from an airplane with an open parachute, his downward velocity t seconds into the fall is v(t) = 20(10.2) feet per second. (a) Use functional notation to express the velocity 3 seconds into the fall. Calculate it. ft per sec (b) Explain how the velocity increases with time. Include in your explanation the average rate of change from the beginning of the fall to the end of the first second and the average rate of " change from the fourth second to the fifth second of the fall. This answer has not been graded yet. (c)-Find the terminal velocity. ft per sec (d) Compare the time it takes to reach 99% of terminal velocity here with the 25 seconds it took a skydiver with his parachute closed to reach 99% of terminal velocity in Example 2.1. On the basis of the information we have, which would you expect to reach 99% of terminal velocity first, O feather feather or a cannonball? O cannonball Need Help? Read It

An engineer is testing how quickly a car accelerates from rest. The velocity V is measured in miles per hour, as a function of time t, in seconds, since the car is at rest. See the table below. What is the slope for the linear function modeling velocity as a function of time, V=,  and what would the formula be for the velocity at time 0, V(0) Time (t) Velocity (V) 2.0 28.9 2.5 35.0 3.0 41.1 3.5 47.2

Starting from the first floor, a lift stops at floors 3, 4,3, 2, 3, and 4 before returning to the first floor. When two consecutive floors are the same, it means that the elevator stayed on the same floor on that segment of the trip. If the distance between the first and sixth floors is 17 m, what is the total distance, d (in m), travelled by the lift? Just enter the number below, correct to one decimal place, without the units. d = Type your answer.

Suppose your hair grows at the rate of 1/34 inch per day. Find the rate at which it grows in nanometers per second. Because the distance between atoms in a molecule is on the order of 0.1 nm, your answer suggests how rapidly atoms are assembled in this protein synthesis.
