Recap - Hit the Target

Part of the Mechanics section of Coddy's Physics journey. Lesson 40 of 97.

Challenge

At a fair you kick a ball at $30^\circ$ above the ground to ring a bell $h = 4.9\ \mathrm{m}$ above the point of the kick. The ball should touch the bell at the very top of its path. Find the launch speed $\relax v_{0}$ .

Try it yourself
