IF R and H represent horizontal range and maximum height of the projectile, then the angle of projection with the horizontal is

A

`tan^(-1)((4)/(5))`

B

`tan^(-1)((5)/(4))`

C

`tan^(-1)((5)/(8))`

D

`tan^(-1)((8)/(5))`

Text Solution

Verified by Experts

The correct Answer is:
C
`because u_(x)=40` and `u_(y)=25`
`therefore tan theta=(u_(y))/(u_(x))=(25)/(40)=(5)/(8)`

The horizontal range and the maximum height of a projectile are equal. The angle of projection of the projectile is

If R and H are the horizontal range and maximum height attained by a projectile , than its speed of prjection is

Assertion: For projection angle tan^(-1)(4) , the horizontal range and the maximum height of a projectile are equal. Reason: The maximum range of projectile is directely proportional to square of velocity and inversely proportional to acceleration due to gravity.

If the maximum vertical height and horizontal ranges of a projectile are same, the angle of projection will be

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A: Horizontal range of a projectile is always same for angle of projection theta with horizontal or theta with vertical . R : Horizontal range depends only on angle of projection .

For a projectile 'R' is range and 'H' is maximum height

A stone projected with a velocity u at an angle (theta )with the horizontal reaches maximum heights H_(1) . When it is projected with velocity u at an angle (pi/2-theta) with the horizontal, it reaches maximum height H_(2) . The relations between the horizontal range R of the projectile, H_(1) and H_(2) , is
