How Do You Calculate Thrust for a Rising Model Helicopter?

Click For Summary
SUMMARY

The thrust exerted by the rotor blades of a model helicopter with a mass of 5.0 kg, rising with constant acceleration to a height of 60 m in 10 seconds, is calculated to be 55 N. To derive this, one must first determine the acceleration using kinematic equations, followed by applying Newton's Second Law to analyze the forces acting on the helicopter. The weight of the helicopter is 50 N, which is a crucial factor in calculating the net force required for the ascent.

PREREQUISITES
  • Understanding of kinematic equations for motion analysis
  • Familiarity with Newton's Second Law of Motion
  • Basic knowledge of free body diagrams
  • Concept of net force and weight calculation
NEXT STEPS
  • Study kinematic equations for uniformly accelerated motion
  • Learn how to apply Newton's Second Law in various scenarios
  • Practice drawing and analyzing free body diagrams
  • Explore the relationship between mass, weight, and acceleration
USEFUL FOR

Physics students, engineering students, and hobbyists interested in model helicopter dynamics and thrust calculations.

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.
