- Can someone help me with this question please A 1.38 kg block is shot horizontally from a spring, and travels 0.468 m up a long a frictionless ramp before coming to rest and sliding back down. 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.As shown in the figure below, a box of mass m = 9.60 kg is slidine across a horizontal frictionless surface with an initial speed v, = 3.40 m/s when k = 2950 N/m. encounters a spring of constant The box comes momentarily to rest after compressing the spring some amount x Determine the final compression x (in m) of the spring. 0.2 Can you write an expression for the initial kinetic energy of the box in terms of its mass and initial speed? What is the final kinetic energy of the box? How is the change in kinetic energy related to the initial and final kinetic energy? Since only conservative forces are acting on the system (box and spring) is energy conserved? How is the change in spring potential energy related to the change in kinetic energy of the box? How is the compression of the spring related to the change in potential energy of the spring and the spring constant? mWhat is potential energy if spring haselastic constant of 4.50x10^4 and equilibrium position of a force of 1.50x10^3N
- o 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 amlaIn the figure below a 1.24-kg block is held at rest against a spring with a force constant K 700 N/m. Equibium paition di Rou gh pctch O=A Initially, the spring is compressed a distance d. When the block is released it slides across a surface that is frictionless, except for a rough patch of width = 4.89 cm that has a coefficient of kinetic friction k= 0.554. Calculate a such that the block's speed after crossing the rough patch is 2.44 m/s.A10.0kgblock is released from pointAin the Figure below.The track is friction-less except for the portionBC, of length6.00 m. The block travels down thetrack, hits a spring with springconstantk, and compresses it0.300 mfrom its equilibrium position before coming to rest momentarily. If thecoefficient of kinetic friction between surfaceBCand block is μk= 0.328, what is the value of thespring constant k?
