M = 3000 kg g = 9.8 m/s² T = 33000 a = ? Ma = Mg - T 3000 * a = 3000 * 9.8 - 33000 3000a = 29400 - 33000 3000a = - 3600 a = - 1.2 m/s².

Mg - T = Ma 3000 * 9.8 - 33000 = 3000* a 29400 - 33000 = 3000 * a -3600/3000 = a a = - 1.2 m/s2

Given, Weight, M = 3000kg Tension, T = 33000N g = 9.8m/s^2 a= ? We have, Mg - T = Ma ie, (3000*9.8) - 33000 = 3000 * a a = ((3000*9.8) - 33000)/3000 = -1.2m/s^2 therefore the elevator is moving up with an acceleration of 1.2m/s^2

33000-3000*9.8=3000*a 33000-29400=3000*a 3600/3000=a

33000-g.3000 = a.3000 With usual meaning of symbols. a negative means movement is downward & vice versa.

Physics - The Science Cube

Equate F (net) = ma Then T - mg = ma (assume all vectors in + Y direction as positive) 33000 - 3000 X 9.8 = 3000 a a = 1.2 m/s² This essentially means that the net force on the elevator is making it move up with an acceleration of 1.2 m/s² See my lecture notes for...
