d=vi*t+1/2a*t^2
vf=vi+a*t
vf^2=vi^2+2a*d
d=((vi+vf)/2)*t
what is kinematics equations
F=m*a
newton's second law
what are vector's and scalars
what is vector's being numbers that can have a direction as in left right up or down and scalars being numbers that can't have direction and are just there
equation for work
what is F*x*cos(theta)
K=n/m
The Spring Constant
a cannon which can shoot a ball at 200m/s takes 15.3 seconds to hit a tree what was the acceleration of the ball from the cannon
what is 13.1
difference in static and dynamic movement
what is no movement for static and movement for dynamic
solve for x
2x+47*2= 92

if a pulley has the power of 128 watts what's the velocity that a 420n force pull can pull it up.
what is .31m/s
elastic equation and definition
m1*v1+m2*v2
elastic problems are when an object will separate due to one having a greater speed or while standing still one moving suddenly then the other will go the other way
if a colt was running back to it's mom which is 229m away and was running at 2.74m/s how long would it have taken for the colt to get back to it's mom?
what is 83.6s
a moving with a force of 2849N to the east has a friction of 320N west what is the net force
what is 2529
397259297839238792350 is what in scientific notation
3.97x10^20
if you had a force pulling up on a object going to the right how much work is being done to the object
what is nothing
inelastic equation and definition
m1*v1+m2*v2=(m1+m2)v
when 2 objects moving to a point where contact is imminent will then stick together and remain connected
a ball hits the wall going 390m/s and a acceleration of 8.3. it also had a time of 29s. what was the initial velocity
what is 149m/s
what is the equation for force parallel and force perpendicular
Fg cos(Θ )=Fperpendicular
Fgsin(Θ )=Fparallel

what is 77.7m
Mr. Smith was rolling a cart of books that had a mass of 30kg down the school hallways when he suddenly slips and pushes the cart faster down the hallway at 3m/s. luckily enough Mr James caught the cart 15s after it was propelled forward. what was the force the cart had before being stopped
what is 6n
