(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A box of mass 5.0 kg is pulled vertically upwards by a force of 68 N applied to a rope attached to the box. Find a) the acceleration of the box and b) the vertical velocity of the box after 2 seconds.

2. Relevant equations

ma = Force and a = T/m -g

a = 68/5 - 9.8 = 3.8 m/s^2

v = vo + axt

v = 0 + 3.8 x 2 = 7.6 m/s.

Does this look right?

Thanks!
