Problem

Two blocks of masses

2\,\text{kg}

and

4\,\text{kg}

are released simultaneously from the same height on a frictionless plane inclined at

25^\circ

. Which statement about their acceleration down the plane is correct? a) Both blocks accelerate at

g\cos25^{\circ}

down the plane. b) The

4\,\text{kg}

block accelerates faster because of its greater weight. c) Both blocks have the same acceleration equal to

g\sin25^{\circ}

. d) Both blocks move with zero acceleration since no friction acts along the plane.
