Problem

During the impact between a bat and a ball, the force on the ball varies as follows: • It increases uniformly from

0

100\,\text{N}

in the first

0.01\,\text{s}

. • Immediately after that, a constant backward force of

20\,\text{N}

acts for

0.02\,\text{s}

. Ignoring all other forces, what is the net impulse on the ball? (a)

0.9\,\text{N\,s}

(b)

0.5\,\text{N\,s}

(c)

0.1\,\text{N\,s}

(d)

-0.1\,\text{N\,s}
