Question

When is H=R/4
When is H=R/2
During projectiles

Answer 1

Answer:

both the cases are when the range is maximum the first is when we have projected an object and second is when we are assuming we have projected the object

Answer 2

Answer:

h=r/4 when the angle theta is 45 degrees

h=r/2 when the angle theta is 2/tan theta

Explanation:

h= u square sin square theta/2g

r=u square sine 2 theta/2g

use the formula and equate according to the equations given and u will get the answer

hope it will help u solve a little on your own and grow ur confidence
