1.	The speed with which a bullet can be fired is 150ms^(-1). Calculate the greatest distance to which it can be prjected and also the maximum height to which it would rise.
Answer» Solution :`R=(U^(2)sin2alpha)/(g)=((150)^(2)SIN90^(@))/(9.8)=2295.1m` `H_(max)=(u^(2)SIN^(2)alpha)/(2g)=((150)^(2)sin^(2)45^(@))/(2xx9.8) = 573.97m`
