You have a formula, just substitute in,

a = 2(.3) / (.9^2) = .74 m/s^2

Thermal said:Unfortunately, I can't help him. The problem is this: a=2d/t(squared). Distance=30 cm. t=.9 seconds.

gfak25's point is that there is no question in there! you give us a formula, and two numbers. Yes, we can

In this case, the whole point of the formula is to

a= (2)(30 cm)/(0.9 s)
