Short Answer

In a physics lab experiment, a compressed spring launches a metal ball at a angle. Compressing the spring causes the ball to hit the floor below the point at which it leaves the spring after traveling horizontally. What is the spring constant?

The spring constant is

See the step by step solution

Step by Step Solution

Step 1: Given information

Compression of the spring

The weight of the metal ball

The launching angle

The horizontal distance traveled

The vertical distance traveled

Step 2: Explanation

When the ball hits the floor the vertical (y) and horizontal distance (x) are 1.5 and 5 respectively. respectively.

By using the equation of motion

By using energy conservation:
