Two people push on a boulder to try to move it. the mass of the boulder is 815 kg. one person pushes north with a force of 65 n. the other pushes west with a force of 42 n. predict the magnitude of the acceleration (in m/s2) of the boulder. assume that friction is negligible.

Explanation:

As the 2 force directions are perpendicular (North vs West), we can calculate the magnitude of the net force using the following equation

Assuming negligible friction, from here we can calculate the acceleration in accordance to Newton's 2nd law of motion
