Here's the entire problem:
A proton is released in a uniform electric field, and it experiences an electric force of 5.8 X 10 ^ (-14) N toward the south. What is the direction of the electric field? The possible answers are:

a.) toward the north
b.) toward the south
c.) toward the east
d.) toward the west

Which one is it? (If you can, also explain why you chose that answer.) Thanks for your help!

"In this lab, a graph of acceleration versus applied force is to be found. Wh would you expect this graph to be linear?"

Why? Because as you apply the force it will accelerate because F=m/a?

Does it mean that even in the air we are travelling at the same speed of the vehicle?

Getting old, and need a refresher course! I would appreciate it if anybody could help me understand this a bit more.
The assumption is starting at zero velocity at hover, where the thrust is equaling the downward force due to its mass.

Our grating is from a Frey Scientific cat.no.17912, and the package says they have 500 lines/mm. For some reason, from the angle that we are getting by shining a red laser pointer through, we are calculating the wavelength of red light to be almost twice as much as it should be. What's going on?

p=psxe^-z/H
p=(ps/RT)xE^-z/H
M=ps/g
ps=surface area
R-gas constant
g=acceleration due to gravity
H=scaleheight

A.) Truck 1=
B.) Truck 2=

You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal mass(3,000 kg each) were involved in a rear-end accident at a stop sign. here is what you know:
Truck 1 approched the intersection from the top of a 22-meter hill.
Truck 2 was on a flat stretch of road directly in front of truck 1.
At the bottom of the hill, before braking for the stop sign, Truck 1 was going 20 m/s and truck 2 was going 35 m/s.
From the skid marks on the road you can see that truck 1 applied force on its brakes for 2 seconds, 80 meters before the stop sign.
There were no skid marks left by truck 2. The collision occured at the stop sign, where truck 2 had stopped.
After the collision, both trucks were moving together in the same direction at 10 m/s, before slowly rolling to a stop.
You must now push truck 2 using 1,000 N of force, 8 meters off the side of the road so no one else gets hurt.
