Question: A 2-kg block is initially held at rest on a wedge of 3 kg in mass, as shown in the figure below. 0 m

A 2-kg block is initially held at rest on a wedge of 3 kg in mass, as shown in the figure below. 0 m (a)

A 2-kg block is initially held at rest on a wedge of 3 kg in mass, as shown in the figure below. 0 m (a) Assuming the wedge cannot move, if its slope is 0-30 and the coefficient of kinetic friction between the block and the wedge is K = 0.1, what is the magnitude of acceleration of the block down the incline? (b) What are the vertical and horizontal components of the acceleration of the block. (c) What fraction of the block's initial potential energy will be converted to heat as the block slides down the wedge? (d) If the wedge in part (a) can move and assuming there is no friction between the wedge and the ground under it (but there is still friction between the block at the wedge), what force would have to be applied to the wedge to stop it from sliding? (e) If no force was applied to stop the wedge in part (d) from moving what would be the initial acceleration of the block as it slides down the incline?
