What is the upward acceleration of a helicopter with a mass of 5000 kg if it is pushing itself up with a force of 59,000 n? remember that gravity is pulling it down with a force equal to mass x acceleration

The upward acceleration, a = 21.6 m/s²

Explanation:

Given,

The mass of the helicopter, m = 5000 Kg

The net force on the helicopter, F = 59000 N

The net force acting on the helicopter is

                                         F = ma + mg

Where,

                 mg - the force due to gravitation

                  a - the upward acceleration of the helicopter

Solving the above equation for 'a'

Substituting the given values in the above equation

                                         a = 21.6 m/s²

Hence, the upward acceleration of the helicopter is, a = 21.6 m/s²

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
