Initial Cart Velocity before Impulse

APPH12-BVRW1$

A $25 \text{ kilogram}$ cart is moving and a force begins to act on it. The force increases uniformly with time from zero to $50 \text{ Newtons}$ over a time of $10\text{ seconds}$ as shown in the graph below. The final velocity of the cart is $3\text{ m/s}$.

What is the best value for the initial velocity of the cart?
