Forces acting on the person, the normal strength of quality and lift the weight of the person in
Scale to determine the scale of the normal
Newton's second law tells us
Sum of forces = ma
In this way,
N - mg = ma
Steps, if N of 0.62 from those of normal weight, then we will
0.62mg-mg = ma or 3.72m/s/s =- =- 0.38 g
Acceleration is negative what would happen if the elevator starts from rest and begins to fall or rise and fall begins at the bus stop
