I'm not gonna ask ffor answers, I just needa know what equations to use and online tutor things are so not helpful

i kind of forgot all my formulas over the break...

Listing in givens w/any info necessary, and what nees to be found

GIVEN
Initial Velosity
Height
Gravity(-9.81m/s^2)
[Projectile shot off a cliff at the height, theta=0]
FIND
time
delta-x

GIVEN
Velocity
Angel
[Projected at an angel at (x,y)=(0,0)
FIND
delta-x

GIVEN
Mass-1 (KG)
Mass-2 (KG)
Velocity of Mass 1
[v of m2 = 0]
FIND
Velocity of both together

GIVEN
Mass
Velocity
Time
[object is going from Vi to rest in the timespan]
FIND
Acceleration (will be negative)
magnitude of F causing acceleration
delta-x


Thank you thank you SO much

Re: Halp, Mechanics review IDK how to do this.

eh, I don't know what equations to use either but I'll look through my physics book for all the equations possible and see if I can match them :/
