A toy helicopter flies forward with a force of 15 N into an oncoming wind of 10 N. The force of gravity pulls the helicopter down with a force of 5 N, but the propeller is providing an upward force of 10 N
To find the net force acting on the helicopter, we need to calculate the sum of all the forces acting on it.
Force of forward flight = 15 N
Force of oncoming wind = -10 N (opposite direction)
Force of gravity = 5 N (downward)
Force of propeller = 10 N (upward)
The net force is the sum of all the forces:
Net force = Forward flight force + Oncoming wind force + Gravity force + Propeller force
Net force = 15 N + (-10 N) + 5 N + 10 N
Net force = 20 N
Therefore, the net force acting on the toy helicopter is 20 N.
To find the net force acting on the toy helicopter, you need to calculate the vector sum of all the forces acting on it.
Given:
- Force flying forward: 15 N
- Force of the oncoming wind: 10 N
- Force of gravity: 5 N
- Upward force provided by the propeller: 10 N
Step 1: Calculate the total force in the horizontal direction (forward):
The net force in the horizontal direction (forward) is the force flying forward minus the force of the oncoming wind:
Net horizontal force = Force flying forward - Force of oncoming wind
= 15 N - 10 N
= 5 N
Step 2: Calculate the net force in the vertical direction (up or down):
The net force in the vertical direction is the sum of the upward and downward forces:
Net vertical force = Upward force provided by propeller - Force of gravity
= 10 N - 5 N
= 5 N
Therefore, the net force acting on the toy helicopter is 5 N forward (horizontal direction) and 5 N upward (vertical direction).
