Suppose a migrating bird flies at a constant altitude of 5 km, with a velocity of 42 km/h. At time t = the bird passes directly above a radar station, where t is measured in hours. (a) How fast is the distance between the bird and the radar station changing after 10 minutes? Round your final answer to 2 decimal places and provide units. (b) How fast is the distance between the bird and the radar station changing at time t = 0, i.e. when the bird is directly above the radar station? Is this reasonable? Explain briefly.

a train is traveling west at 60mile/h and at t=4s later it is traveling north at 60mile/h.  find the average a(arrow) (/a(arrow)/ and theta)

You are sitting in your car at a red light when you see a zombie standing still 65m in front of your car. You both begin to accelerate towards each other. Your car accelerates at 1.8 m/s^2 and the zombie accelerates at 0.6 m/s^2. How long does it take for you to strike the zombie?   Make sure to include a diagram of the physical situation, label known and unknown quantities with units, and coordinate system. Thanks!

Tutorial Exercise A soccer ball is kicked from 2 feet above the ground. The height, h, in feet of the ball after t seconds is given by the function h = -16t2 + 64t + 2. (a) Graph the function. (b) At what time(s) is the height of the ball 50 feet? Step 1 Create a table of values for the function. [AlgUns.0386] The height function is h = -16t2 + 64t + 2. Create a table of values for the ordered pairs of the form (t, h). th = -16t² + 64t + 2 %3D 1 2 4 Submit Skip (you cannot come back)
