A box starts from rest and is pushed a distance d = 1.25 meters along a frictionless ramp by a horizontal force, Fa, in 9.75 seconds. The mass of the box is m = 25.0 kg. The ramp is inclined at an angle of θ = 23.5â-¦ above the horizontal.
(a) What is the acceleration of the box as it slides up the ramp?
(b) What is the magnitude of horizontal force Fa?
(c) What is the magnitude of the normal component of the force exerted on the box by the ramp?
