block X as shown. Calculate the magnitude of the
force exerted by block X on block y during this
acceleration

Answers
1). Eclipse
2). Circle
3). Sphere
4). Great circle
5). Triangle

Explanation
1). When a cylinder is bisected diagonally is forms a shaped that looks like an eclipse.
2). A cone has circular base. If it is cut such that it cross-section is parallel to the base then it will be a circle.
3). When you rotate a semi-circle about its axis it will form a sphere.
4). If a sphere is cut along its widest part it would form the great circle.
5). A triangle is formed when a cone is cut from the vertex to the centre of its base.
