Questions
A projectile is thrown at a angle of 15o with the horizontal and the range is 1.5 km. What is the range when it is projected at 45o ?
detailed solution
Correct option is D
The range R of the projectile is given byR=u2sin2θgIn first case, 1⋅5=u2sin(2×15)g=u22gIn second case, R=u2sin(2×45)g=u2g=1⋅5×2=3kmTalk to our academic expert!
