CBSE Class 12-science Answered
The maximum height attained by a projectile is
increased by 5%. Keeping the angle of projection
constant, what is the percentage increase in horizontal
range?
Asked by kumarshee | 19 Apr, 2013, 12:42: PM
Expert Answer
Relation between range (R) and maximum height (H) is given by
tan@ = 4H/R where @ is the angle of projection
so to keep @ constant, R should be increases by same amount by which maximum height increases
since H is increased by 5%, R should also be increased by 5% ..
