Problem

Blocks A, B and C move along the same straight line with the following initial (

v_{i}

) and final (

v_{f}

) velocities: • A:

m=1\,\text{kg}

v_{i}=+5\,\text{m/s}

v_{f}=-3\,\text{m/s}

• B:

m=2\,\text{kg}

v_{i}=+2\,\text{m/s}

v_{f}=+7\,\text{m/s}

• C:

m=3\,\text{kg}

v_{i}=-4\,\text{m/s}

v_{f}=-1\,\text{m/s}

Arrange the magnitudes of impulses received by the blocks in decreasing order. (a)

A > B > C

(b)

C > B > A

(c)

B > C > A

(d)

B > A > C
