A block whose mass is 5.7 kg slides on horizontal frictionless table top with a constant speed of 5 m/s. It is brought momentarily to rest by compressing a spring in its path. By what maximum distance is the spring compressed? (spring constant of spring, K = 1282.5 N/m)

10. A block with mass 0.50 kg is forced against a horizontal spring of negligible mass, compressing the spring a distance of 0.20 m (Fig. P43). When released, the block moves on a horizontal table top for 1.00 m before coming to rest. The spring constant k is 100 N/m. What is the coefficient of kinetic friction between the block and the table top? Figure P43 k- 100 Nim -0.50 kg 1.00 m-

A block of mass 1.7 kg is attached to a horizontal spring that has a force constant 800 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. x x=0 (a) A constant friction force of 3.7 N retards the block's motion from the moment it is released. How much is the spring compressed when the speed of the block is a maximum. 0.463 cm (b) What is the maximum speed? Your response differs from the correct answer by more than 10%. Double check your calculations. cm/s

A 88.47 kg student is standing atop a spring in an elevator that is accelerating upward at 1.94m/s2. The spring constant is 1467 N/m. By how much is the spring compressed?

To measure the static friction coefficient between a 1.40-kg block and a vertical wall, a spring (k = 770 N/m) is attached to the block, is pushed on the end in a direction perpendicular to the wall until the block does not slip downward (see figure). If the spring is compressed by 0.048 m, what is the coefficient of static friction?

An ideal spring is attached to the ceiling. While the spring is held at its relaxed length, a wooden block (M = 850 g) is attached to the bottom of the spring, and a ball of clay (m = 210 g) is pressed onto the bottom of the block so that they stick together. The block+clay are gently lowered through a distance of d = 2.7 cm and are then released, at which point they hang motionlessly from the bottom of the spring. After a few minutes have passed, the clay unsticks itself from the block and falls from rest to the ground. 1. What is the resulting period T of the block’s oscillation after the separation occurs? 2. As d approaches 0, what limit does T approach?

A 5.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.500 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)? (Enter a number.)N/m   i tried 5.00 x 10^5 and i don't think it was correct..

A block with a mass of 30.0 kilograms (kg) is held against a spring with a force constant of k = 1.25×105 N/m. The spring is initially compressed 17.5 centimeters (cm) from equilibrium. Then the block is released, setting it into motion. The block initially slides along a frictionless surface, but then it encounters a 1.50 meter long rough patch where the coefficient of kinetic friction is 0.134. It then slides down a frictionless ramp, which is tilted at an angle of 19.5 degrees and has a length of 2.50 meters. How fast is the block moving when it reaches the bottom of the ramp? Give your answer in meters per second (m/s). Hint: use WNC = ΔK + ΔU.

An elastic cord is 66 cmcm long when a weight of 73 NN hangs from it but is 87 cmcm long when a weight of 190 NN hangs from it.What is the "spring" constant kk of this elastic cord?

Your doctor has told you to watch your weight. Of course, your weight comprises two factors, so you assume that she wants you to watch both your mass and the local value of g. Which explains why you are carrying a small mass mm on an elastic band wherever you go. Most of the time, the elastic band is stretched by a distance of 2.1 cm. However, when you have finished lunch, you go into a very tall building and take the high speed lift (or elevator depending on where you live). Soon after the doors close, you notice that the band (which has linear elastic properties) is stretched by a total distance of 3.5 cm. a) At what rate is the lift accelerating? _____ m.s−2 b) Your doctor will want to know the factor by which your weight has increased after that lunch. Suppose that you stand on scales in the lift while it is accelerating as described above. According to the scales, your weight has increased by a factor of _____ My answers are a)6.6 and b)1.67 but they're wrong.
