In a physics lab experiment, a compressed spring launches a 30 gmetal ball at a 25 ∘ angle. Compressing the spring 19 cm causes the ball to hit the floor 1.7 m below the point at which it leaves the spring after traveling 6.0 m horizontally.

What is the spring constant?

As part of an experiment in physics lab, small metal ball of radius r = 2.3 cm rolls without slipping down a ramp and around a loop-the-loop of radius R = 3.4 m. The ball is solid with a uniform density and a mass M = 373 g. How high above the top of the loop must it be released in order that the ball just makes it around the loop? Now instead of a sphere, what if we rolled...

In our physics lab, we did a experiment regarding Hooke's law, and the goal is to find the spring constant by using a simulation. In the first section of the procedure, our instructor intentionally give us the wrong instruction, which tells us to find spring constant using varying mass, delta x and constant gravity. In the second section of the procedure, we need to figure out what went wrong in the first section that caused us to incorrectly measure the...
