thank you soooooo much(:
A projectile is shot horizontally at 220 m/s from the top of a 620 m high cliff. A) How long till the projectile hits the ground? B) How far from the base of the cliff does the projectile land? I am gonna be honest. I have no idea how to do any of my Physics homework. ): I sti...

A tennis player places a 51 kg ball machine on a frictionless surface, as shown below. The machine fires a 0.067 kg tennis ball horizontally with a velocity of 33.4 m/s toward the north. What is the final velocity of the machine? Can you please EXPLAIN how to get the answer?!
A 66.5 kg ice skater moving to the right with a velocity of 2.80 m/s throws a 0.16 kg snowball to the right with a velocity of 20.4 m/s relative to the ground. (a) What is the velocity of the ice skater after throwing the snowball? Disregard the friction between the skates and...

Okay, so you have two variables, let's call them x and y. x will be the weight of the water when the tank is full, and y will be the weight of the tank. So you can get two equations from the question: .4x+y=80 (1) x+y=140 (2) and now you can do elimination by subtracting (...
