Sleds propelled by rockets are used to study how humans react to sudden acceleration. If a rocket-powered sled accelerates to a speed of 442.82 m/s in 1.71 seconds, what is the sled's acceleration (measured in meters per second squared)? Only the final answer, stated to three decimal places, should be rounded off.
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
A 7760 kg space probe, moving nose-first toward Jupiter at 73.9 m/s relative to the Sun, fires its rocket engine, ejecting 83.0 kg of exhaust at a speed of 248 m/s relative to the space probe. What is the final velocity of the probe? Number Units
-L.1971+38.67 Time (in seconds) The driver of a vehicle applies the brakes, softly at first, then harder, coming to a complete stop after 7 sec. The velocity as a function of time is modeled by the function v(t) = -1.197t² + 58.67,. where v is in feet per second, t is in seconds and 0sis 7. How far did the vehicle travel while the driver was braking? Velocity (in feet per second)
1) A race car travels around a circular race track for which the start line and finish line are at the same location. If the race is 888km long and the radius of the track is 1.414km, how many times did the car go around the track? The race takes 2 hours and 45 minutes, what is the race car’s average velocity (in m/s) over the entire race? What is the race car’s average speed (in m/s) over the entire race?
(b) Suppose instead that the true speed of the car as a function of time is described by v(t) = 30√/t (still from t = 0 to t = 4). Sketch a graph of the car's speed vs. time. (c) Since the speed is no longer constant, it is much harder to calculate the distance traveled. But we can still try. Suppose we wanted to calculate how far the car went in the sin minute from 1:00 and 1:01. i. Let's pretend that the car's speed is constant for this single minute. What might be a reasonable approximation for the car's speed, in this scenario? (There is no one single correct answer to this question; make your best estimate.) ii. Under this assumption, approximately how far did the car go during this minute? (Hint: Don't forget that a minute is hours.) 60
