Q1. What's about solidification of metal oxide vapour onto oxide substrate? E.g.ZrO2 on metallic or ceramic substrates at EB-PVD process.
Q2. The weight of the block in the drawing is 56 N. The coefficient of static friction between the block and the vertical wall is 0.440. (a) What minimum magnitude of the force is required to prevent the block from sliding down the wall?(Hint: The static frictional force exerted by the block is directed upward, parallel to wall.) (b) What minimum force is necessary to start the block moving up the wall? (Hint: The static frictional force is now directed down the wall.)
A professor's office door is 0.9 wide, 2.0 high, and 4 thick; has a mass of 25; and pivots on frictionless hinges. A "door closer" is attached to door and top of the door frame.

An ice block is pushed horizontally on a frictionless surface with initial velocity v0. At some point, it comes to the nearly semicircular bump with a radius R=0.42m and the height h=0.33m above the ground.
What is the speed of projectile immediately before it hits the ground if air friction does one and a half times as much work on projectile when it is going down as it did when it was going up.
A baseball pitcher can throw a ball with a speed of 70m/s. He is in the back of a pickup truck that is driving away from you. He throws the ball in the direction, and it floats toward you at a lazy 10 m/s.
