A horizontal spring with spring constant 30 N/m is compressed by 5 cm by a 10 gram mass. After the mass is released, it accelerates due to the potential energy of the spring. Use conservation of energy to determine what speed the 10 gram mass reaches after being pushed by the spring Answer in units of m/s and round to 3 significant figures

1.A spring-loaded dart gun with a spring constant K= 2000 N/m is used to shoot a dart with a mass .20kg straight up into the air, and the dart reaches a maximum height of 10 meters. How far did the spring need to be compressed? 2. If i wanted to measure the amount of potential energy in the spring inside my nerf gun, with some nerf darts, what is an easy way i could do it? Explain the steps you...
A Hooke's law spring constant k=7 220 N/m is compressed 12.0 cm from equilibrium using a 1 kg mass starts to move up on a frictionless inclined plane. Find the velocity immediately after it is released. Find its potential energy as it moves up 3 meters.
A spring whose spring constant is 1000 N/m is compressed by 10 cm. By how much does its mass increase in its compressed state?
A rock is thrown straight vertically upward with an initial velocity of 15 m/s. Ignore energy lost to air friction. The rock will rise to a maximum height of The velocity of the rock at half that maximum height is A Hooke's law spring is compressed 12 cm from equilibrium and the potential energy stored is 3.6 J. The spring constant in this case is The spring is then used to launch a mass of 50 gram along a frictionless...
1. A 30 cm spring with constant 70 N/m is compressed to 10 cm and placed between two carts. Cart A has mass m Skg and mg is unknown. Initially the system is at rest. After it is released it is observed that cart A has three times the velocity of cart B. a) What force must be exerted initially to keep the spring compressed? b) What is the work done to compress the spring? c) By considering conservation of...
A spring-powered dart gun is un-stretched and has a spring constant 150 N/m. The spring is compressed by 8.00 cm and a 5.00 gram projectile is placed in the gun. The maximum height of the projectile when it is shot at an angle of 30.0 degrees above the horizontal from the gun is...?
Question 7 (10 points) A spring with a spring constant 4.7 N/cm is compressed 45 cm and released. The 15 kg mass skids down the frictional incline of height 45 cm and inclined at 25° angle. The acceleration is 9.8 m/s2. The path is frictionless except for a distance of 1.0 m along the incline which has a coefficient of kinetic friction Hk = 0.35. What is the final velocity Vf of the mass? 45 cm Too0000 15 kg u...
