Problem

A student pulls a

1.0\,\text{kg}

cart with a horizontal force that increases uniformly from

0\,\text{N}

t=0

10\,\text{N}

t=0.50\,\text{s}

and then is removed. The track is frictionless. What is the magnitude of the impulse delivered to the cart during the

0.50\,\text{s}

interval? a)

3.5\,\text{N}\!\cdot\!\text{s}

5.0\,\text{N}\!\cdot\!\text{s}

2.5\,\text{N}\!\cdot\!\text{s}

1.3\,\text{N}\!\cdot\!\text{s}
