A test aircraft shows, immediately after take-off, a trajectory
with the Cartesian equation: Y = 5*10-5
x2
It moves as the expression x = 150t + 5t2 , where "t" is
in seconds and X results in meters.
Determine the position, speed and acceleration of the aircraft when
t= 10 seconds.

The flight path of a jet aircraft as it takes off is defined by the parametric equations x= 1.2t^2 and y = 0.04t^3where t is the time after take-off, measured in seconds, and x and y are given in meters. At t = 50 s (just before it starts to level off), determine (a) the horizontal distance it is at from the airport, (b) its altitude, (c) its speed and (d) the magnitude of its acceleration.

5.) Immediately after take-off an airplane moves with 400 km/h at an angle of 10° with respect to the horizontal. A passenger moves from the front of the plane toward the back of the plane with 10 km/h. Determine the velocity of the passenger with respect When reading this problem the first thing is to look for what’s given. Since we see that the velocity is equal to 400 km/h ,and the passenger moves from the front of plane towards...
