How Do You Calculate Thrust for a Rising Model Helicopter?

In summary, the question asks for the thrust exerted by the rotor blades of a model helicopter that rises from rest to a height of 60 m in 10 seconds with a mass of 5.0 kg. The answer is 55 N and the solution involves using kinematics equations and Newton's 2nd Law.

Dynamics question please help i am stuck...!

A model helicopter of mass 5.0 kg rises with constant acceleration from rest to a height of 60 m in 10 seconds. Find the thrust exerted by the rotor blades during the ascent


The answer to this question according to the booklet is 55 N
Please show the working too and the concept apply to come up with the answer

My attempt

Thrust denote as F

weight 50 N..then i am stuck i don't really know what to do

Step 1: Use the kinematics equations to find the acceleration
Step 2: Draw a free body diagram of the rising helicopter, write Newton's 2nd Law and solve for the thrust.
 

FAQ: How Do You Calculate Thrust for a Rising Model Helicopter?

What is the definition of "model helicopter accelerating"?

Model helicopter accelerating refers to the increase in speed of a miniature helicopter, typically controlled by a remote or a pilot, as it moves through the air.

How is the acceleration of a model helicopter measured?

The acceleration of a model helicopter is typically measured in meters per second squared (m/s^2) or feet per second squared (ft/s^2). This can be calculated by dividing the change in velocity by the change in time.

What factors can affect the acceleration of a model helicopter?

The acceleration of a model helicopter can be affected by various factors such as the weight of the helicopter, the power of the motor, the angle of the rotor blades, and the air resistance. These factors can either increase or decrease the acceleration of the helicopter.

How does the acceleration of a model helicopter differ from a real helicopter?

The acceleration of a model helicopter is typically much faster and more responsive compared to a real helicopter. This is because model helicopters are smaller, lighter, and have more powerful motors, allowing them to accelerate at a faster rate.

What are some practical applications of studying model helicopter acceleration?

Studying model helicopter acceleration can have various practical applications, such as improving the design and performance of real helicopters, understanding the physics of flight, and developing better remote control systems. It can also be used in the field of robotics to improve the agility and speed of flying drones and unmanned aerial vehicles.
