1.	In the question number 62, the distance from the thrower to the point where the ball returns to the same level is
Answer» 58 m 68 m 78 m 88 m Solution :The DSITANCE from the thrower to the point where the ball RETURNS the same leve is `R=(u^(2)sin2theta)/(g)=((30ms^(-1))^(2)(SIN60^(@)))/(10ms^(-2))~~78`
