In the figure here, two children are playing a game in which they try to hit a small box on the floor with a marble fired from a spring- loaded gun that is mounted on a table. The target box is horizontal distance D = 2.18 m from the edge of the table. Bobby compresses the spring 1.18 cm, but the center of the marble falls 25.6 cm short of the center of the box. How far should Rhoda compress the spring to score a direct hit? Assume that neither the spring nor the ball encounters friction in the gun. 00000 Number i Unit

In the figure here, two children are playing a game in which they try to hit a small box on the floor with a marble fired from a spring-loaded gun that is mounted on a table. The target box is horizontal distance D = 2.23 m from the edge of the table. Bobby compresses the spring 1.16 cm, but the center of the marble falls 29.9 cm short of the center of the box. How far should Rhoda compress the spring to score a direct hit? Assume that neither the spring nor the ball encounters friction in the gun.
Answer the question in full details, thank you very much, Answer on the correct significant figures: A metal can containing condensed mushroom soup has a mass of m = 247 g, a height of h = 15.7 cm,and a diameter of D = 6.67 cm. Itis placed at rest on its side at the top of a L = 3.11 m-long incline thatis at an angle of Angle = 24.3 deg to the horizontal; the can is then released to roll down the incline, reachingthe bottom t = 1.53 s later. Assuming energy is conserved, calculate the moment of inertia of the can inkg-cm^2 (not kg-m^2).
A 0.1000-kg marble is fired by a boy from a slingshot at point A, at a height of 1.500 m from the ground. It hits a frictionless inclined concrete wall at point B, which is 30.0 m away from the boy. After hitting the wall, the marble rebounds with a velocity, VB. directed 140° from the horizontal as shown. The ball finally hits point C on the frictionless floor. The velocity of firing, VA, is 20.0 m/s, directed 45.0° with the horizontal.

At a waterpark, sleds with riders are sent along a slippery, horizontalsurface by the release of a large compressed spring. The spring,with force constant k = 40.0 N/cm and negligible mass, rests on thefrictionless horizontal surface. One end is in contact with a stationarywall. A sled and rider with total mass 70.0 kg are pushed against theother end, compressing the spring 0.375 m. The sled is then releasedwith zero initial velocity. What is the sled’s speed when the spring(a) returns to its uncompressed length and (b) is still compressed 0.200 m?
