### Explanation of Helper Springs in Truck SuspensionsTruck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by the distance \( y_0 \), the helper spring engages and then helps to support any additional load.#### Diagram DescriptionIn the diagram:- **Truck body**: The upper part of the figure (labeled in green) represents the body of the truck.- **Main leaf spring**: This is a primary suspension component mounted on the axle and attached to the truck body. It is shown in gold color.- **Helper spring**: This is a secondary spring, depicted in gray, which engages when the main leaf spring is compressed beyond a certain point.- **Axle**: The central horizontal component connecting the wheel to the springs.The distance \( y_0 \) (0.500 m) indicates the initial compression needed for the helper spring to engage.Suppose the leaf spring constant is \( 5.20 \times 10^5 \) N/m, and the helper spring constant is \( 3.70 \times 10^5 \) N/m. These constants determine the stiffness of the springs.#### Questions for Calculation(a) **What is the compression of the leaf spring for a load of \( 4.20 \times 10^5 \) N?** - Enter your answer in meters.(b) **How much work is done in compressing the springs?** - Enter your answer in joules.

You push a 2.00 kg block against a horizontal spring, compressing the spring by 15.0 cm. Then you release the block, and the spring sends it sliding across a frictionless tabletop for 30.0 cm. The block then moves up an 30.0°-incline plane and it moves up the incline for 65.0 cm before coming to rest. If the spring constant is 1000.0 N/m, determine the coefficient of kinetic friction between the block and the incline plane.

Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 45 N/m, attached to a 34-kg block in an incline (0 = 37°).
