Three concurrent forces are applied to keep a 150N weight in equilibrium. Two of the forces are given by F1= (-3i-25j+16k)N
F2 = (14i+16j+88k).
Assuming that the force of gravity is along the z-axis, determine the components of the third force.​

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
