Question: The mass m = 3.96 kg is sliding on the frictionless incline of angle 42.7 degrees as shown. A force F = 3.24 N is applied horizontally as shown. Compute the acceleration a (in m/s2) of the mass on the incline. Use g = 9.8 m/s2, take parallel to the plane & up the plane as positive, and express your result to three significant digits. Be careful with signs!
