please please answer super super fast Please only answer part c, d, and e
**Problem 3:** Two blocks are connected by a light but sturdy string wrapped around a mass-less pulley. The rough inclined surface makes an angle of 30 degrees with the horizontal. The block on the inclined surface has mass \( M = 45.2 \, \text{kg} \). Assume the coefficient of kinetic friction between the block of mass \( M \) and the inclined plane is \( \mu_k = 0.10 \). The vertically hanging block has mass \( m = 9.0 \, \text{kg} \). Assume the blocks begin their motion from rest. (a) What is the magnitude \( N \) of the normal force on the block of mass \( M \)? (b) What direction does the hanging block \( m \) move, up or down? Circle one. (c) What is the common magnitude \( a \) of the acceleration of the blocks? (d) What is the magnitude \( T \) of the tension in the string? (e) What is the speed of the hanging mass after a time period of 2.0 seconds? **Diagram Explanation:** The accompanying diagram shows: - A right triangle representing the inclined plane, with an angle labeled as \( 30^\circ \). - A block of mass \( M \) on the inclined plane. - A string running over a pulley at the top of the inclined plane. - A hanging block of mass \( m \) suspended vertically from the pulley. The forces in this system include gravitational force acting on both masses, tension in the string, frictional force against mass \( M \) on the incline, and the normal force perpendicular to the inclined surface.
