again again and again thank you for the help everyoneGotta do my physics review someone help with questions?
a.) 4000
do your own homeworkGotta do my physics review someone help with questions?
51. a.) 4000
When the resultant force is zero, an object is either at rest or going through a motion with constant velocity.
52. a.) 47
u=0m/s, t=4.8s, a=9.81m/s2, v=?
v = u + at
v = 0 + (9.81)(4.8)
v = 47.088m/s
57. d.) all of the above
60. b.) the bugs velocity changes the mostGotta do my physics review someone help with questions?
Hey, I learned calculus from wikipedia.
Do a search for %26quot;kinematics%26quot; the study of motion acceleration distance velocity and time.
My prayers are you with and all the other troops serving over in Afghanistan.
