car seat table tops

car seat table tops
I need some help with these physics problems! Thanks for your help!?

A block is sitting at rest on a table. As I start to push on the block parallel to the table top with increasing force, the force of friction acts as follows
-force of friction decreases as my force increases until it reaches zero and the block moves
-force of friction increases as my force increases until it reaches its maximum possible value, and then the block moves
-force of friction is constant as my force increases until my force is greater than the force of friction and the block moves
-none of the above are true

A car makes a banked turn on a “real” road (meaning you can not ignore friction), which of the following are forces that act on the car: (select ALL that are true)
centripetal force
friction
normal force from the road
weight of the car

You are driving a car with a friend sitting in the front passenger seat. Your friend is not wearing a seat belt. If you want to make your friend slide into you, do you make a sharp right or a sharp left turn?

1. Force of friction is constant as my force increases until my force is greater than the force of friction and the block moves

2. ALL

3. A Sharp Right, unless you are in London and the passenger its on the other side, in that case, a Sharp Left.
