Question
**Calculating the Magnitude of the Normal Force**

The normal force is the force exerted by a surface to support the weight of an object resting on it. In this exercise, we will calculate the magnitude of the normal force on a \(17.7 \, \text{kg}\) block in various scenarios. Enter your answers in Newtons (N).

**(a)** The block is resting on a level surface.
- Incorrect response indicator: ✗
- Answer box to enter the normal force in N.

**(b)** The block is resting on a surface tilted up at a \(40.8^\circ\) angle with respect to the horizontal.
- Answer box to enter the normal force in N.

**(c)** The block is resting on the floor of an elevator that is accelerating downward at \(3.28 \, \text{m/s}^2\).
- Answer box to enter the normal force in N.

**(d)** The block is on a level surface, and a force of \(145 \, \text{N}\) is exerted on it at an angle of \(40.8^\circ\) above the horizontal.
- Answer box to enter the normal force in N.

For each scenario, consider the forces acting on the block and use the appropriate equations to calculate the normal force.
