Question 1 Report

A stone, Q is thrown with velocity U at an angle of 75o to the horizontal. Another stone R is thrown with the same velocity U but with an angle of 15o to the horizontal. The ranges covered by the stones will be

greater for Q

greater for R

the same for Q and R

greater for the heavier of the two stones

Answer Details

Range =

\frac{U^{2} s i n 2 θ}{g}

RangeQ = $\frac{U^{2} s i n 150}{g}$

RangeR = $\frac{U^{2} s i n 30}{g}$

Since, sin30o = sin150o

therefore, RQ = RR
