A vertical spring with elastic constant 95 N/m is compressed by 25 cm, and an object of mass 350 g is placed on top.  When released, the spring will move upward, and the object will lose contact with the spring at its uncompressed position.  What is the maximum height above the uncompressed position this object will attain?

A spring-loaded toy gun is aimed vertically and fired after a spherical projectile of mass m = 29.5 g is loaded by compressing the spring with force constant k = 820 N/m a distance of 8.90 cm. As the projectile travels a total distance of 56.6 cm along the barrel of the gun, it experiences a friction force of 1.50 N. What is the height reached by the projectile above its initial location with the spring compressed? ?m

5:29 PM Sun Nov 5 Tt S 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 210g) 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 it- self from the block and falls from rest to the ground. What is the resulting period T of the block's oscillation after the sep- aration occurs? For the limit check, investigate what happens to T if the block+clay only need to be lowered through an extremely short distance (d → 0) before they can be released motionlessly. = ✪ 4% =

A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.80 kg, and the spring has a spring constant of 59 N/m. The coefficient of static friction between the box and the table on which it rests is μs = 0.74. How far can the spring be stretched from its unstrained position without the box moving when it is released?

A factory worker drops a 10 kg steel block from rest. The block falls 30 cm onto a vertical spring standing on the floor. The spring constant of the spring is 400 N/m. Once the block has made contact with the spring, it continues to move downward, compressing the spring until it comes to rest. (The spring then decompresses, firing the block upward.) Determine the distance that the spring was compressed by the block. Assume two significant digits in given data.

A spring-loaded toy gun is aimed vertically and fired after a spherical projectile of mass m = 28.0 g is loaded by compressing the spring with force constant k = 830 N/m a distance of 9.20 cm. As the projectile travels a total distance of 56.0 cm along the barrel of the gun, it experiences a friction force of 2.00 N. What is the height reached by the projectile above its initial location with the spring compressed?

A solid tungsten block of mass m is pressed against a spring of force constant k. As a result, the spring is compressed a distance x. The spring then expands and pushes the block to the right. The block, therefore, slides up the incline and eventually stops. If we repeat this activity but this time compress the spring a distance of 2x k m 0000000- Smooth Smooth

A 0.250-kg block along a horizontal track has a speed of 1.50m/s immediately before colliding with a light spring of force constant 4.60 N/m located at the end of the track. What is the spring’s maximum compression if the track is frictionless? If the track is not frictionless, would the spring’s maximum compression be greater than, less than, or equal to the value obtained in part (a)?

A 5.00-kg block is moving at 6.00 m/s along a frictionless, horizontal surface toward a spring with force constant k=500 N/m that is attached to a wall (the figure (Figure 1)). The spring has negligible mass. Find the maximum distance the spring will be compressed. If the spring is to compress by no more than 0.550 m , what should be the maximum value of v0?

A large toy car is pushed horizontally by a spring, and the spring has a spring constant of 135 N/m. What is the mass of the toy car if compressing the spring 0.055 m (before the toy starts moving) causes it to reach a speed of 0.75 m/s? (Note - the height of the toy does not change.) What equation will be best for calculating this value? Your answer: O mgh, = O mgh, =mv? %3D 0 글씨로=mghy
