Question

Consider a box of mass 10 kg being lifted upward by a person standing on the surface of the earth. At a given instant the box is being accelerated upwards with an acceleration of size 5 m/s2. Find the force that the person exerts on the box at this instant.

Answer 1

Hi..


We know that ..
Force = mass * acceleration.

Thus ..
F = 1000g * 5 ms^-2.
F=5000N.


Hope this helps u!!
