Superman wanted to launch a small rocket using a spring mounted vertically on the ground. He placed the 4.0 kg rocket on a very stiff spring. The spring is 1.5m long, it has negligible mass and a spring force constant of 100,000 N/m. He compresses the spring for 1.1m. He then releases the spring. If y = 0 at the ground level, the system consists of the rocket and the spring; (I) what is the energy of the system before Superman releases the rocket? (II)What is the maximum height the rocket can reach if we can neglect air resistance? (III) If air resistance can’t be neglected, it exerts a constant force of 37.5N on the rocket, how high will the rocket reach? (IV) What is the speed of the rocket when it is 120.0 m from the ground if air resistance is taken into account?
Two 2 kg carts are connected by a compressed spring of stiffness 5 J/cm2. Starting from rest, the spring decompresses by 1 cm, sending the carts in opposite directions. a) What is the speed of each of the carts after the spring is released?
A 10-kilogram block is dropped from point A as shown. The rail is frictionless except for the 6 m long B and C parts. The block slides down the rail and hits a pedestrian with k = 2250 N / m and stops for a moment by compressing the spring by 30 cm according to the balance position. Find the kinetic friction coefficient between the B and C part of the rail and the block.
A spring with spring constant 23 N/m is compressed a distance of 8.0 cm by a ball with a mass of 219.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 8.0 cm and is also released, leaving the spring at point A. Assume the ball rolls, but ignore other effects of friction. (Assume that the ball is a solid ball.) (a) What is the speed of the ball at point B?(b) What is the speed of the block at point B?
If a 4-kg block is placed against the spring and the spring is released, what will be the speed of the block when it separates from the spring at x =0? Neglect any friction in the problem.
A 0.250 kg dart is fired into a stationary 1.20 kg block of wood that is on a frictionless surface (of course!). The dart and block then impact a spring with a spring constant of k = 1120 N/m and compresses it 0.360 m. (Use g = 10 m/s2, as needed. Do not enter units in numerical answers.) What is the total energy stored in the spring, in Joules, when it is fully compressed? ____ What is the speed, in m/s, of the dart-block combination after the collision? ____ How fast was the dart moving, in m/s, before it hit the block of wood?
The desperate contestants on a TV survival show are very hungry, but the only food they can see is some fruit hanging on a branch high in a tree. Fortunately, they have a spring they can use to launch a rock which has a spring constant of 1600 N/mN/m . They can compress the spring by a maximum of 18.1 cmcm and they choose a rock that has a mass of 679 gg . With what speed does the rock leave the end of the spring? If they hope to dislodge a piece of fruit using their device, what is the highest the fruit could be above the end of their spring?
A 4.50 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.900 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)?
A 0.100 kg block of ice is placed against a horizontal, compressed spring mounted on a horizontal tabletop that is 1.50 m above the floor. The spring has force constant 2000 N/m and is initially compressed 0.045 m. The mass of the spring is negligible. The spring is released, and the block slides along the table, goes off the edge, and travels to the floor. If there is negligible friction between the block of ice and the tabletop, what is the speed of the block of ice when it reaches the floor?
In a needle biopsy, a narrow strip of tissue is extracted from a patient with a hollow needle. Rather than being pushed by hand, to ensure a clean cut the needle can be fired into the patient's body by a spring. Assume the needle has mass 5.60 g, the light spring has force constant 440 N/m, and the spring is originally compressed 8.10 cm to project the needle horizontally without friction. (The spring is fully uncompressed before the needle contacts the skin.) The tip of the needle then moves through 2.40 cm of skin and soft tissue, which exerts a resistive force of 7.50 N on it. Next, the needle cuts 3.50 cm into an organ, which exerts a backward force of 9.70 N on it. (a) Find the maximum speed of the needle. m/s(b) Find the speed at which a flange on the back end of the needle runs into a stop, set to limit the penetration to 5.90 cm. m/s
