- Homework Statement
- A 100g ball on a 60 cm string is swung in a vertical circle about a point 200 cm above the ground. The tension in the string when the ball is at the very bottom of the circle is 5.0N. A very sharp knife is suddenly inserted when the ball is parallel to the ground to cut the string. What is the distance the ball will land after the string is cut.

- Relevant Equations
- T - mg = m(v^2/r)

delta y = v_y(t) + 1/2at^2

delta x = v_x(t)

So first I found the velocity of the ball at the bottom of the swing from the force equations, which I got to be 4.9 m/s and this is only in the x-direction. Then using the projectile motion for delta y I found time, which is 0.2s. Then using that time I found the delta x to be 0.98m.

I just want to make sure my work is correct and concise.
