Explanation / Answer

Positive is left to right, negative is right to left.

for broccoile momentum p = mv
p = 0.207kg * 1.51m/s = 0.31257 kg m/s

p = mv
p = 0.335 * -2.27 = -.0.76045 kg m/s

Net momentum = 0.31257 -.0.76045 = -0.44788 kg m/s

The delectable dish moves 0.44788 N*s from right to left

p = mv

0.44788 = (.0.207 + 0.335) v

v = 0.826 m/s
