A missile is moving 1350 m/s at a 25.0 degree angle. It needs to hit a target 23500 m away in a 55.0 degree direction in 10.20s. What is the direction of its final velocity?

V=

Direction is normal to the incline

Explanation:

This question tests on projectile motion.

First, calculate the acceleration of the missile.

Incline=55º,Distance=23500m, t=10seconds.

Horizontal motion of projectile

Final velocity

The vertical motion of the missile can be calculated as:

Final Velocity is:

Combining both we get

*Misile's motion is normal to the 55º incline.
