A jet with mass m = 9 10⁴ kg jet accelerates down the runway for takeoff at 1.6 m/s².

What is the net horizontal force on the airplane as it accelerates for takeoff?

_N

What is the net vertical force on the airplane as it accelerates for takeoff?

_N

Once off the ground, the plane climbs upward for 20 seconds. During this time, the vertical speed increases from zero to 23 m/s, while the horizontal speed increases from 80 m/s to 97 m/s.

What is the net horizontal force on the airplane as it climbs upward?

_N

What is the net vertical force on the airplane as it climbs upward?

_N

After reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 12 seconds.

What is the net horizontal force on the airplane as it levels off?

_N

What is the net vertical force on the airplane as it levels off?

_N

Scientists want to place a 3300 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2414 m/s in a perfectly circular orbit. Here is some information that may help solve this problem:

m_mars = 6.4191 x 10²³ kg r_mars = 3.397 x 10⁶ m G = 6.67428 x 10^-11 N-m²/kg²

What radius should the satellite move at in its orbit? (Measured frrom the center of Mars.)

_m

What is the force of attraction between Mars and the satellite?

_N

What is the acceleration of the satellite in orbit?

_m/s²

What should the speed of the orbit be, if we want the satellite to take 8 times longer to complete one full revolution of its orbit?

_m/s
