Sam is pulling a box up to the second story of his apartment via a string. The box weighs 16.5 kg and starts from rest on the ground. Sam is pulling so that the velocity of the box is increasing by 2.6 m/s every second.

How long until the box reaches a height of 13.2 m?

Answer:

Weight (mass) = 16.5 kg

velocity = 0 m/a

acceleration =2.6 m/s^2

displacement = 13.2m

now,

acceleration = velocity/ time

2.6 = 0 / t

t = o / 2.6

t = o
