Projectile motion -- I could use some help studying example problems please

[wib]

Homework Statement

I have a test coming up in projectile motion, and I understand very little of it. Like calculating hang time, horizontal range, max height etc.

Homework Equations

ΔY=vyiΔt+1/2ay(Δt)^2
Quadratic formula
There shouldn't be any math past Algebra I

Welcome to the PF.

Post an example problem here using the Homework Help Template like you tried to fill out above, and we should be able to help you study. There are more Relevant Equations (like how is the velocity related to acceleration, etc.), and you will usually use F=ma in your solutions.

Post a sample question and do your best to solve it, and we will give you some hints on what you are not seeing...

Homework Statement

Tom the cat is chasing Jerry the mouse across a table surface 1.5m high . Jerry steps out of the way at the last second, and Tom slides off the edge of the table at a speed of 5 m/s.
A. Where will Tom strike the floor?
B. What are his vertiacl and horizontal velocity components just berfore he hits the floor?

Homework Equations

ΔY=vyiΔt+1/2ay(Δt)^2
Δx=vxit
My class rounds gravity from 9.81 to 10

The Attempt at a Solution

-1.5=0+1/2(-10)t^2
t=0.55
so Δx=(5)(0.55)
=2.8m

I really like your OP

Tom the cat is chasing Jerry the mouse

For the first question
+) y = 0 = h - (gt^2)/2 => t
+) x = Vo*t => x
