u $$sin$$ $$300$$ $$=$$ $$80$$ ⇒u $$=$$ $$160$$ $$m/sux$$ $$=$$ u $$cos300$$ $$=$$ $$160$$ $$32$$ $$=$$ $$803$$ $$m/sT$$ $$=$$ $$2usin300g$$ $$=$$ $$2$$×$$8010$$ $$=$$ $$16$$ svy $$=$$ $$uy-gT4$$ $$=$$ $$80-10$$×$$164$$ $$=$$ $$40$$ $$m/sv$$ $$=$$ $$vx2+vy2$$ $$=$$ $$(803)2+402$$ $$=$$ $$145$$ $$m/s$$

A projectile is fired at an angle $30^{0}$ to the horizontal such that the vertical component of the initial velocity is 80 m/s. Find approximately the velocity of the projectile at time $\frac{T}{4}$ where T is time of flight.
