A toy gun uses a spring to project a 4.6-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 14 cm long, and a constant frictional force of 0.031 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 6.5 cm for this launch? (Assume the projectile is in contact with the barrel for the full 14 cm.) m/s

1. A marble is fired into the air at 12m/s at an angle of 35° from vertical. It lands 1.25 m lower than its launch height. What is the maximum height that it reaches above its landing location? When does it reach this height? When does it land? What is its velocity (speed and direction) when it lands? Max height Time at max height = Time of landing- Velocity at landing - 2.

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...

A spring gun is made by compressing a spring in a tube and then latching the spring at the compressed position. A 4.97-g pellet is placed against the compressed and latched spring. The spring latches at a compression of 4.07 cm, and it takes a force of 9.12 N to compress the spring to that point. (a) If the gun is fired vertically, how fast is the pellet moving when it loses contact with the spring? (Include the effect of...
