Question

the weight of an helicopter is 5000N and the earth gravity is 10K/Kg calculate the weight

Answer 1

Given:

Mass of the helicopter is, 1000kg

The total mass of crew and passengers is, 300kg

Acceleration of the helicopter, a=15m/s2

Total mass of the system, mt=1300kg

(a)

The reaction force applied by the crew and passengers on the floor of the helicopter is given by:

R−mg=ma

      =m(g+a)

      =300×(10+15)=7500N

So, the force exerted by the passengers on the floor is 7500 N
