Suppose a block with mass 2.30kg is resting on a ramp. If the coefficient of static friction between the block and the ramp is 0.420.

1. What maximum angle can the ramp make with the horizontal before the block starts to slip down?

2. What is the new coefficient of static friction if the maximum angle turns out to be 38.0 degrees?

3. Find the maximum static friction force that acts on the block.
