A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of46 ft/s. Its height in feet after t seconds is given by y = 46t – 21t2.A. Find the average velocity for the time period beginning when t=2 and lasting.01 s:.005 s:.002 s:.001 s:NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator.Estimate the instanteneous velocity when t=2.

The initial velocity of the bal, u = 46 ft/sThe height in feet after t seconds, y = 46t -21t2

At 10:17 a.m., you pass a police car at 55 mph that is stopped on the freeway. You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.
A rabbit runs across a parking lot on which a set of coordinate axis has been drawn. The coordinates of the rabbit’s position as a function of time t are given by: x = -0.3t2 + 5t + 28 and y = 0.22t2 - 8t + 30 with t in seconds and x and y in meters. What is the velocity at t= 10 sec? A. 0.6 i + 0.4 j B. -0.2i +1.6j +30 C. -i - 3.6 j D. 4i + 2j
George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his velocity in meters per second? Also, is the acceleration due to gravity negative or positive or it depends? I'm really confused. Please help and explain in an easy to understand.
