The grenade is a point mass that is thrown with a variable velocity \(u\), at a variable angle \(\theta\). The barrier is a cylinder with a radius of \(R= 2m\).
Find the minimum value of \(u\) (in meters) for which the particle crosses the log.
Details and assumptions
Neglect air resistance and viscosity.
Take \(g=9.8 m/s^2\).
