115. A canoe with a mass of 200 kg is moving along with a speed of 12 mfs When it passes by a second canoe with a mass of so} kg, the second canoe transfer 50 kg of its mass to the first canoe directiy across
{perpendicular to} the motion {lowering its mass to 251:! kg}. assume that the canoes cannot move sideways= so all changes in velocity occur parallel to their motions. Determine the final velocities of both
canoes in the following cases- a)
b)
C)
d) 6) Explain why the motion of the second canoe is not affected by the 12me
mass transfer: but the motion of the first canoe is affected by it. 2001*
In the first case the second canoe is at rest when it transfers the 0 oh;
513' kg mass.
Inthesecondcasethesecondcanoeismovingwiththesame -’ velocity as the first canoe Twhen rt transfers the Mg mass- In the third case the second canoe is moving with a speed of H} mfs in the same direction as the first canoe when it transfers the fig mass. In the fourth case the second canoe is moving with the same speed as the first canoe hut in the
opposite direction when it transfers the Mg mass.
