Astronauts in space move a toolbox from its initial position →=<15,14,−8>m to its final position →=<17,14,−1>m. The two astronauts each push on the box with a constant force. Astronaut 1 exerts a force 1→=<18,7,−12> and astronaut 2 exerts a force 2→=<16,−10,16>. Required:
What is the total work performed on the toolbox?

If both forces are measured in Newtons, then the net force is

F = (18, 7, -12) N + (16, -10, 16) N = (34, -3, 4) N

The toolbox undergoes a displacement (i.e. change in position) in the direction of the vector

d = (17, 14, -1) m - (15, 14, -8) m = (2, 0, -9) m

The total work done by the astronauts on the toolbox is then

F • d = (34, -3, 4) N • (2, 0, -9) m = (68 + 0 - 36) N•m = 32 J

i think its

they should be similar or the same
