Question

The height attained by a projectile is 25% of range when projected for maximum range

Answer 1

A projectile is thrown so that it covers the range of 100m and the max height attained is 25m. What is the angle of projection?

maximum height can be attained only when the projectile is launched at 90°

threrfore ,

h= u^2/2g

25×2×9.8= u^2

490=u^2

7√10=u

then for range ,

the maximum range occurs at 45°

R = u^2/g

R = 490/9.8

R = 50 m

Answer 2

Answer:

the maximum range occurs at 45°

R = u^2/g

R = 490/9.8

R = 50 m
