Physics

a student apparently weighs 180 lb in an elevator that is accelerating at the rate of 5ft/s^2

a) What is the true weight of the student?
b) What will be the apparent weight of the student when the elevator now decelerates at the rate of 2 ft/s^2?
c) What should be the elevator's acceleration in order for the apparent weight of the student to be equal to 160 lb?

You have not mentioned which way the lift goes, up or down? That will determine what equation to write.

A red ball is thrown straight up from the edge of the roof of a building.A green ball is dropped from the same point 1.80 seconds later.
If the height of the building is 60.0 m , what is the initial velocity of the red ball,if both balls are to hit the ground at the same time?
