An elevator starts from rest with a constant upward acceleration. It moves 5 m in the first 2 s. A passenger in the elevator is holding a 4 kg package by a vertical string. The tension in the string during the accelerating process is ____ N ?

Answer:

Solution:

$s = \frac{1}{2} a t^{2} \Rightarrow 5 = \frac{1}{2} a (2)^{2} \Rightarrow a = 2.5$ m/s $^{2}$

For the package: $T - 40 = 4 \times 2.5$

$T = 50$ N
