Answer:
The maximum height attained by the body is 33.75 m
Explanation:
Given :
A body projected with a velocity 30 m/s at an angle of 30° with the vertical.
To find :
the maximum height attained by the body
Solution :
The maximum height of the projectile is given by,
where
u denotes the velocity of projection
θ denotes the angle made by the projected body with the horizontal
g denotes the acceleration due to gravity ( = 10 m/s² )
Here,
- 30° is the angle with the vertical.
Hence, angle made by the projected body with the horizontal,
θ = 90° - 30°
θ = 60°
- u = 30 m/s
Substituting the values,
Therefore, the maximum height attained by the body is 33.75 m
