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?
A spring with a force constant of 12 N/m rests horizontally on a table and projects balls with a mass of 8.3 × 10-3 kg towards targets placed on the ground 93 cm below. If the spring is compressed by 4.0 cm, how far does the ball travel horizontally before it hits the ground?
(a) A spring of negligible mass and with spring constant k = 400 N/m is hung vertically;
a pan of mass mp = 0.2 kg is suspended from its lower end. A piece of meat of mass
mm = 2.2 kg is dropped onto the pan from a height of 0.4 m above the pan. The
meat makes a totally inelastic collision with the pan, and sets the system into vertical
simple harnoіс тotion.
Find:
(i) the speed of the meat and pan immediately after the collision;
(ii) the amplitude of the subsequent motion; and
(iii) the period of that motion.
