During this time, the vertical speed increases from zero to 24.0 m/s, while the horizontal speed increases from 80.0 m/s to 98.0 m/s. What is the net vertical force on the airplane as it levels off?
It slides while being pushed by the wind with a force of 0.35 N directed along the positive y-axis. Calculate the magnitude of the penguin's velocity at t = 9.95 s.
Two forces F1 and F2 are acting on a mass M = 5kg. The force F1 = 7i + 6j + 2k, in N. The acceleration of the mass is given by a = 2i + 7j + 5k, in m/s^2. Calculate the magnitude of F2.
