A helicopter propeller applies an upward force of 2800 N. The force of gravity on the helicopter is 2000 N. Another person of weight 950 N grabs the helicopter and holds on
1.) can the helicopter take off with the person holding on?
2.) Why or why not? (answer in terms of forces and directions)

3.) how much force would the propeller need to produce to perfectly balance the forces on the helicopter?
​
