physics homework help; how do you find magnitude?

Question

okay the question says "what is the magnitude of the acceleration of the wagon..." there isn't a formula to finding out magnitude so what is it?

Answer 1

Magnitude is just a number, so it's the number you get when you do use an equation for acceleration.

Answer 2

"Magnitude " can be replaced with the term "total value" if you like. Sometimes its used when you are studying "vectors" because it becomes the magnitude of the sum of the vectors in a coordinate system. I am not sure of your specific problem but if there is an acceleration vector in two perpendicular directions you need to use Pythagorean theorem to get the equivalent "magnitude" sum.

Answer 3

The magnitude is how large something is. The direction (+,-)does not mater. In this case it does not mater if the wagon speeds up or slows down: just give the number. The acceleration a is the change in speed (v) devided by the change in time (t) in which the change in speed occured. a = v / t

Answer 4

magnitude is any number
formula
a= (v-u)/t
a= acc
v = final vel
u = ini vel
t = time

Answer 5

formulas for finding acc
1)a=(v-u)/t
if final velocity (v),initial velocity(u) and time(t) is given
2){(v^2)-(u^2)}/2s=a
if v , u ,and distance travelled(s) is given
3){2(s-ut)}/t^2
when s ,u ,t is given

Answer 6

a=dv/dt=ddx/dtdt
