If the ramp makes an angle of 45.0° with respect to the horizontal, and the spring originally was compressed by 0.14 m, find the spring constant.
- Please as soon as possibleo Harry is designing the crumple zones in a new car. He decides to model the front end of the car as a spring. If he wants it to bring the car (mass m) to rest from an initial velocity to without the passengers experiencing an acceleration of more than ama, what spring constant should he use? mal amla16. A mass is sitting on a frictionless table and attached to one end of a spring. The spring Is horizontal and the other end of the spring is attached to a wall. The spring is initially at its natural length. I give the mass a very quick push, giving it an initial velocity vo away from the wall, as shown in the diagram below. Wall Spro The mass moves away from the wall and then back towards the wall as the spring stretches and then recoils. What is the direction of the net force on the mass in the middle of this motion, when it is instantaneously stopped, just before moving back towards the wall? A) Zero net force B) Horizontal towards the wall C) Horizontal away from the wall Đ) Vertically downwards E) Vertically upwards

The larger the opposite from its equilibrium its equilibrium by F-kr, at. In Haiti, public transportation is often by taptaps, small pickup trucks with seats along the sides of the pickup bed and railings to which passengers can hang on. Typically they carry two dozen or more passengers plus an assortment of chickens, goats, luggage, etc. Putting this much into the back of a pickup truck puts quite a large load on the truck springs. A truck has springs for each wheel, but for simplicity assume that the individual springs can be treated as one spring with a spring constant that includes the effect of all the springs. Also for simplicity, assume that all four springs compress equally when weight is added to the truck and that the equilibrium length of the springs is the length they have when they support the load of an empty truck.
