How Do You Calculate Thrust for a Rising Model Helicopter?

AI Thread Summary
To calculate the thrust for a model helicopter rising with constant acceleration, first determine the acceleration using kinematics. Given the mass of the helicopter is 5.0 kg and it rises to 60 m in 10 seconds, the acceleration can be calculated as 1.2 m/s². The weight of the helicopter is 50 N (5.0 kg x 9.8 m/s²). Applying Newton's second law, the thrust must overcome both the weight and provide the necessary upward force, resulting in a total thrust of 55 N. This calculation confirms the answer provided in the booklet.

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.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
