Ajetliner of mass 8.70×104 kg is in level flight when it encounters a downdraft (a downward wind) that lasts for 1.20 s . the vertical component of the jetliner's velocity is 71.5 m/s after the downdraft subsides. what is the downdraft's average force, f, on the jetliner?

The downdraft's average force is F= 5.18 *10⁶ N.

Explanation:

m= 8.7 * 10⁴ kg

V= 71.5 m/s

t= 1.2 s

F*t= m*V

F= m*V/t

F= 5.18 *10⁶ N

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
