You have a new internship, where you are helping to design a new freight yard for the train station in your city. There will be a number of dead-end sidings where single cars can be stored until they are needed. To keep the cars from running off the tracks at the end of the siding, you have designed a combination of two coiled springs as illustrated in Figure P7.41. When a car moves to the right in the figure and strikes the springs, they exert a force to the left on the car to slow it down. Both springs are described by Hookes law and have spring constants k1 = 1 600 N/m and k2 = 3 400 N/m. After the first spring compresses by a distance of d = 30.0 cm, the second spring acts with the first to increase the force to the left on the car in Figure P7.41. When the spring with spring constant k2 compresses by 50.0 cm, the coils of both springs are pressed together, so that the springs can no longer compress. A typical car on the siding has a mass of 6 000 kg. When you present your design to your supervisor, he asks you for the maximum speed that a car can have and be stopped by your device. Figure P7.41
Q6) If a spring moves 150 cm when a force of 5 N is applied what is the spring constant?
2. Mang Juan connected a spring to a wall, mounted horizontally. Juana his daughter pulls the spring to the right stretching the spring by 30 cm. If the pulling force exerted on the spring is 90 N, calculate the spring constant of the spring.
DNA molecules are typically folded tightly. Stretching a strand of DNA means straightening it, and the molecules resist this straightening. Investigators can attach beads to the ends of a strand of DNA and, using “optical tweezers,” measure the force required to produce a certain extension. Data for the stretch of a 3500 base pair strand of DNA approximately follow the line in the graph shown. What is the spring constant for this strand of DNA?
Q13: The block shown is released () from rest with the spring unstretched (). The pulley and the horizontal surface are frictionless. If k = 490N / m and M = 3kg what is the maximum extension of the spring?

A 8.0 kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown in (Figure 1). What does the spring scale read just before the mass touches the lower spring? The scale reads 16 NN when the lower spring has been compressed by 1.7 cmcm. What is the value of the spring constant for the lower spring? At what compression length will the scale read zero?

A small steel ball bearing with a mass of 14 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.35 m. Calculate the horizontal distance the ball will travel if the same spring is aimed 26degrees from the horizontal. Use kinematic equations Fast pls i will rate
A toy car is launched by compressing a horizontal spring by 0.05 m and then releasing it as shown in the figure below. The mass of the toy car is 0.23 kg. The speed of the car after it is launched down the horizontal track is 2.4 m/s. What is the spring constant? You can assume that the track is frictionless and that the toy car starts from rest. Give you answer in N/m and report your answer to 1 decimal place.
