During an episode of turbulence in an airplane you feel 180 N heavier than usual.
Part A
If your mass is 86 kg, what are the magnitude and direction of the airplane’s acceleration? 2sf
please help The pulley system shown in the figure is used to lift a m= 67-kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume the masses of the chains, pulleys, and ropes are negligible.
Determine the force F required to lift the crate with constant speed.
Express your answer using two significant figures.
F = kN
Part B
Determine the tension in the upper chain.
Express your answer using two significant figures.
Cupper = kN
Part C
Determine the tension in the lower chain. c upper= kn
To find the magnitude and direction of the airplane's acceleration, we can use Newton's second law of motion:
Force = mass * acceleration
In this case, the force experienced is the apparent increase in weight, which is 180 N. The mass of the person is given as 86 kg.
Rearranging the equation, we can solve for acceleration:
acceleration = Force / mass
Substituting the values:
acceleration = 180 N / 86 kg
Calculating the value:
acceleration ≈ 2.09 m/s²
So, the magnitude of the airplane's acceleration is approximately 2.09 m/s².
Since the person feels 180 N heavier, the direction of acceleration is downward (towards the ground).
