Question
A 67-kg fisherman in a 131-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.7 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown. magnitude m/s directionA 67-kg fisherman in a 131-kg boat throws a package of mass
m = 15 kg
horizontally toward the right with a speed of
vi = 4.7 m/s
as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown.
magnitude m/s direction ---Select--- toward the right toward the left upwards downwards ma TExplanation / Answer
Apply conservation of momentum
final momentum = initial omentum
(67 + 131)*v + 15*4.7 = 0
v = -15*4.7/(67 + 131)
= -0.356 m/s
magnitude of velocity of the boat after the package is thrown,
|v| = 0.356 m/s <<<<<<<-------Answer
direction : toward the left <<<<<<<-------Answer
