A child exerts a force of 2.0N [forward] on a stationary 4.0kg tricycle for 1.2 seconds. Calculate the acceleration of the tricycle.
So... All i could think of is given : force of 2.0N, Time of 1.2s and a mass of 4.0kg.
Required: Acceleration
Analysis: Im not sure which formula to use? I cant use a = velocty/time because I do not know velocity... and i cant use V=a x time because i dont know veloctiy. Im confused? Please help? Thanks!

Excellent! That worked... thats wierd because I dont even know that equaton? So F stands for force in that equation?

The time of 1.2 seconds is a red herring; you don't need a time.
All you need for the answer is F=mA or A = F/m.
A = 2.0N/4.0kg.

Behind every formula is some message. Try to understand that message and not just to learn the formula.
