Angle at Maximum Height

In summary, the angle at maximum height is the angle at which a projectile is launched to reach the highest point in its trajectory. It can be calculated using the equation tan(theta) = (vy/vx), and it does affect the distance traveled. The angle cannot be greater than 90 degrees and air resistance can decrease the distance and maximum height reached by the projectile.

Homework Statement



the initial velocity of a projectile is 150 m\s .the angle between the velocity vector and the trajectory at the projectile's maximum height is
a) 90
b) 45
c) zero
d) 63.1
e) 36.9

Homework Equations



Vox= vx = Vocosθ
Vy = Vosinθ-gt
Range (R) = (vo)^2*sin(2θ)/g
Maximum Height (H) = (vo)^2*(sinθ)^2/2g

Correct.
 

1. What is the angle at maximum height?

The angle at maximum height is the angle at which a projectile is launched so that it reaches the highest point in its trajectory.

2. How is the angle at maximum height calculated?

The angle at maximum height can be calculated using the equation tan(theta) = (vy/vx), where vy is the vertical velocity and vx is the horizontal velocity of the projectile.

3. Does the angle at maximum height affect the distance traveled?

Yes, the angle at maximum height does affect the distance traveled by a projectile. A higher angle will result in a shorter distance, while a lower angle will result in a longer distance.

4. Can the angle at maximum height be greater than 90 degrees?

No, the angle at maximum height cannot be greater than 90 degrees. This would result in the projectile traveling straight downwards, rather than reaching a maximum height.

5. How does air resistance affect the angle at maximum height?

Air resistance can affect the angle at maximum height by reducing the distance traveled and the maximum height reached by the projectile. This is due to the drag force acting against the projectile's motion, slowing it down.
