Question

A child's toy consists of a block that attaches to a table with a suction cup, a spring connected to that block, a ball, and a launching ramp. (Figure 1)The spring has a spring constant k, the ball has a mass m, and the ramp rises a height y above the table, the surface of which is a height H above the floor. Initially, the spring rests at its equilibrium length. The spring then is compressed a distance s, where the ball is held at rest. The ball is then released, launching it up the ramp. When the ball leaves the launching ramp its velocity vector makes an angle θ with respect to the horizontal. Throughout this problem, ignore friction and air resistance.

Spring and Projectile - Part A A child's toy consists of a block that attaches to a table with a suction cup, a spring connected to that block, a ball, and a launching ramp. (Figure 1) The spring has a spring constant k, the ball has a mass m, and the ramp rises a helght y above the table, the surface of which is a height H above the floor. Relative to the initial configuration (with the spring relaxed), when the spring has been compressed, the ball-spring system has Initially, the spring rests at its equilibrium length. The spring then is compressed a distance s, where the ball is held at rest. The ball is then released, launching it up the ramp. When the ball leaves the launching ramp Its velocity vector makes an angle with respect to the horizontal o gained kinetic energy gained potential energy lost kinetic energy o lost potential energy Submit Request Answer Throughout this problem, ignore friction and air resistance. Part B As the spring expands (after the ball is released) the ball-spring system o gains kinetic energy and loses potential energy o gains kinetic energy and gains potential energy o loses kinetic energy and gains potential energy oloses kinetic energy and loses potential energy Submit Request Answer Figure 1 of 2 - Part C As the ball goes up the ramp, it o galns kinetic energy and loses potential energy gains kinetic energy and gains potential energy loses kinetic energy and gains potential energy oloses kinetic energy and loses potential energy Submit Request Answer
Hey, please answer part A-G and make sure the answers are correct.

Answer 1

A Compressing a spring gains potential. » ½ kue B) As a spring expands you lose spring potential and therefore it has to go somewhere. So, (A) is correct ता c) Loses kinetic and gains potential Energy Option (1) is correct when an object going up, it looses K.E and gains PE Option (A) is correct. When an object fl. falling from a height - its P.E decreases and KiE increases. E) insufficient data (figure 2) is missing. from low of conservation of energy- Kitui - R { +Uf 0+/kg² = 1/₂ m vg² timgy.
