Question: Point B is 25 km due east of point A. Starting from point A, a camel walks 20 km in a direction 15° south of east and then walks 8.0 km due north. What is the resultant angle?

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
