Compressing a spring. A block of mass m of 1.7 kg and moving along a horizontal surface with speed v of 2.3 m/s runs into and compresses a spring with spring constant k of 320 N/m. (a) By what distance x is the spring compressed? (b) By what distance x is the energy equally divided between potential and kinetic energies? A: (a) 17 cm; (b) 12 cm
You push on a box of 10kg with a force F = (20i −10j )N. It moves on a rough surface (uc = 0.1) over 2 m. The crate is initially stationary. Can you calculate the speed of the crate after 2 m, using the kinetic energy theorem?
Your answer is partially correct. Try again. In the figure, a spring with spring constant k = 180 N/m is at the top of a frictionless incline of angle e = 38°. The lower end of the incline is distance D = 0.92 m from the end of the spring, which is at its relaxed length. A 1.5 kg canister is pushed against the spring until the spring is compressed 0.22 m and released from rest. (a) What is the speed of the canister at the instant the spring returns to its relaxed length.(which is when the canister loses contact with the spring)? (b) What is the speed of the canister when it reaches the lower end of the incline?

A block, mass 3.5kg, compresses a spring (k= 2345N/m) a distance of 25cm and is held at rest there. The block is initially on a surface that has an incline of 45 degrees. The block then travels up the slope to a level surface that is 0.85m above it's original launch height. As it travels along this surface, it encounters a 0.75m patch of a frictional surface with a coefficient of friction of 0.12. Finally, the block hits a spring (k=1234 N/m), compresses it, and comes to rest. How much will the spring compress in order for the box to be at rest?
You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 10-m-high hill, then descends 17 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5 m and that a loaded car will have a maximum mass of 400 kg. For safety reasons, the spring constant should be 13% larger than the minimum needed for the car to just make it over the top. k = 1.4x104 Submit Part B m Previous Answers Correct Correct answer is shown.

What should be the spring constant kk of a spring designed to bring a 1300 kg car to rest from a speed of 85 km/h so that the occupants undergo a maximum acceleration of 5.0gg? Express your answer using two significant figures.
In the figure, a block of mass m = 1.40 kg slides head on into a spring of spring constant k = 220 N/m. When the block stops, it has compressed the spring by 14.0 cm. The coefficient of kinetic friction between block and floor is 0.280. While the block is in contact with the spring and being brought to rest, what are (a) the work done by the spring force and (b) the increase in thermal energy of the block-floor system? (c) What is the block's speed just as the block reaches the spring? (a) Number (b) Number i i (c) Number i Units Units Units 4 ←
a cannonball with a mass of 6.95 kg is placed in a vertical, spring-loaded cannon bearing a spring with a spring constant of 5.6 newtons/meter. The spring is compressed by a distance of 4.54 meters and released. Please use g=9.80 m/s2. The max height reached by the cannonball in meters is?
A 5.00 × 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 spring constant k of the spring?
= 2. Refer to the diagram below. A spring-loaded launcher is aimed vertically upward, and compressed 0.13 m beyond its equilibrium position, then locked into place. The spring constant is k 60000 N/m. A block of mass 2 kg is placed on the launcher. When the spring lock is released, the block is launched upward to a maximum height, H. What is this height, H, if the block loses 17 Joules of mechanical energy to air resistance (during its upward flight)? Show all calculations. пиши before launch H = ? риши after launch
