An 2.1 kg object is launched down a frictionless ramp at 7.2 m/s towards a spring connected to the bottom end of the ramp. The ramp is 44.8 m long and is angled at 48.4o above the horizontal. The spring constant for the spring is 1770 N/m. By how much is the spring compressed by the object? Round final answers to 2 decimal places.
A 6.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.400 m by a large spring bumper at the end of its track. What is the force constant k of the spring?
Truck 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 distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 5.20 x 105 N/m, the helper spring constant is 3.70 x 105 N/m, and y, = 0.500 m. Truck body -"Helper" spring Main leaf spring Axle (a) What is the compression of the leaf spring for a load of 4.20 x 105 N? m (b) How much work is done in compressing the springs?
A 2000 kg (19,600 N) elevator with broken cables in a test rig is falling at 4.00 m/s when it contacts a cushioning spring at the bottom of the shaft. The spring is intended to stop the elevator, compressing 2.00 m as it does so . During the motion a safety clamp applies a constant 17,000 N friction force to the elevator. What is the necessary force constant k for the spring?
O Macmillan Learning A block of mass m = 2.15 kg slides along a horizontal table with speed vo= 1.00 m/s. At x = 0, it hits a spring with spring constant k = 73.00 N/m, and it also begins to experience a friction force. The coefficient of friction is given by μ = 0.100. How far has the spring compressed by the time the block first momentarily comes to rest? Ax = m wwwwwwwww Ax
Good day.I have a question on physics. I searched for the solution to this problem:A force of 36.ON acclerates a 6.0kg block at 7.0m/s2 along a boriztonal surface. How large is the friction force? and opened two solutions. It actually has the same answers but I am wondering if ff and fk are the same?If ff and fk are the same, then Friction Force and Kinetic Friction are the same?Thank you.

Truck body Axle (a) What is the compression of the leaf spring for a load of 4.70 x 105 N? 0.87 Your response differs from the correct answer by more than 10%. Double check your calculations. m (b) How much work is done in compressing the springs? 0.855 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J

A 50 g ice cube can slide without friction up and down a 30º slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 13.0 cm. The spring constant is 25 N/m. When the ice cube is released, what distance (in cm) will it travel up the slope above the release point before reversing direction? Use g = 10 N/kg. In your calculations, make sure you convert to consistent units (kg and meters).
Tendons. Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke’s law. In laboratory tests on a particular tendon, it was found that, when a 248-g object was hung from it, the tendon stretched 1.22 cm. (a) Find the force constant of this tendon in N/m. (b) Because of its thickness, the maximum tension this tendon can support without rupturing is 140 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Draw free-body diagram.
A 252-g object is attached to the end of a horizontal spring. It is pulled with a 7-N horizontal force and is stretched by 11 cm. What is the value of the spring constant in newtons per meter? Round answer to 2 decimal places.
