a 2-kg body rests on a frictionless wdge that as an inclination of 60degrees and an acceleration a to the right such that the mass remains stationary elative to the wedge.

a. find a.

b. what would happen if the wedge were given greater acceleration?

Answer:
a) If the mass remains stationary, it means that the component of its weight down the wedge is balanced by the component of the force acting in the opposite direction (like an artificial gravity)
mgcos30 = acos60
2 x 9.8 x 0.866 = a x 0.5
a= 33.95 m/s^2

b) If the wedge were given greater acc, the body would move up the plane
