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!
