## Homework Statement

A dynamics cart is pulled from rest by a net force of 1.2M [Forward]. The cart moves 6.6m, reaching a velocity of 3.2m/s [Forward].

## Homework Equations

F=ma

## The Attempt at a Solution

I tried using the formula V(final)^2 = V(initial)^2 + 2*a*d to get acceleration and plug it into F=ma to find mass and got 5kg but the textbook says that the answer is 1.5kg
