A rocket is fired from rest at x = 0 and travels along a parabolic trajectory described by y² = 240,000x where "y" is in meters when "x" is in meters. If the "x" component of acceleration is ax = t² in m/s² when "t" is in seconds. Determine the magnitude of the rocket's velocity and acceleration when t= 10 s. 2007

Transcribed Image Text:A rocket is fired from rest at x = 0 and travels along a parabolic trajectory
described by y² = 240,000x where "y" is in meters when "x" is in meters.
If the "x" component of acceleration is ax = t² in m/s² when "t" is in
seconds. Determine the magnitude of the rocket's velocity and acceleration
when t= 10 s.
Ans.
| D|L=105 |
|at=10s| = 206.2 m/s²
=
2007 m/s
