## Homework Statement

Question 2: An airplane is gliding in a direction 10 degrees downward from the horizontal. Three forces act upon it: its weight of 10,000N; the lift, perpendicular to the direction of motion; and the drag of air friction, opposite to the direction of motion. Assume the plane moves with constant speed and compute the value of the lift.

## Homework Statement

Question 3: A 40kg block is place on a level table and a rope is fastened to it which passes horizontally to a pulley at the edge of the table and thence extends downward to a 1.5kg block suspended from the other end. Neglecting friction, calculate the acceleration and direction of the moving blocks.

Ok. After that what do I do?

I am trying to figure out what equations to use!
