Ajet with mass m = 8 × 104 kg jet accelerates down the runway for takeoff at 1.5 m/s2.
i have found out so far
1) net horizontal force(takeoff) = 12
2)net vertical force(takeoff) = 0
once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 20 m/s, while the horizontal speed increases from 80 m/s to 96 m/s.
3)what is the net horizontal force on the airplane as it climbs upward = 64000
i need
4) what is the net vertical force on the airplane as it climbs upward?
