A small cart weighs 15.0 N. If a constant force of 25 N is used to move the cart horizontally across the desk,
A] What will be the acceleration of the cart?

B]How far will the car move in 1.0 second

A:
weight = 15.0N = mg, g = 9.81, you can find mass, 25N = ma, rearrange with your mass value to find acceleration

B:
X = Xo + VoT + 1/2aT^2
Xo=0, Vo=0, so X = 1/2aT^2
