AI Thread Summary
To calculate the average power delivered by the engines during the DC-3 airplane's takeoff, relevant equations include the formula for power, which is work done over time, and the kinetic energy formula. The airplane's mass is 9500 kg, and it reaches a speed of 110 km/h in 9.0 seconds. First, convert the speed to meters per second for accuracy. The work done can be calculated using the change in kinetic energy, and then divide by the time to find the average power. This approach will yield the average power output of the engines during the takeoff phase.

The takeoff of a DC-3 airplane is 110 km/h. Starting from rest, the ariplane takes 9.0 s to reach this speed. The mass of the (loaded) airplane is 9500 kg. What is the average power delivered by the engines to the airplane during takeoff?

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...
