Two groups of canoeists meet in the middle of a lake. After a brief visit, a person in canoe 1 pushes on canoe 2 to separate the canoes. Suppose the speeds of the two canoes after they are pushed apart are 0.60 m/s for canoe 1 and 0.46 m/s for canoe 2.
If the mass of canoe 1 is 310 kg , what is the mass of canoe 2?
____kg
Homework Answers
let,
mass of the canoe, m1=310 kg
mass of the canoe is m2
speed of m1 is v1=0.6 m/sec
speed of m2 is v2=0.46 m/sec
by using law of conservation momentum,
m1*u1+m1*u2=m1*v1+m2*v2
0=310*0.6-m2*0.46
======> m2=404.35 kg
mass of the canoe, m2=404.35 kg

Two groups of canoeists meet in the middle of a lake. After a brief visit, a person in canoe 1 pushes on canoe 2 to separate the canoes. Suppose the speeds of the two canoes after they are pushed apart are 0.52 m/s for canoe 1 and 0.38 m/s for canoe 2. If the mass of canoe 1 is 300 kg , what is the mass of canoe 2?

Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at vA = 2.7 m/s , and ball B is moving to the right along the x axis with speed vB = 5.5 m/s . After the collision, assumed elastic, ball B is moving along the positive y axis(Figure 1). Part A- What is the final direction of ball A? Part...

Q14
An ice cube is floating in a glass of water. After it has melted, has the water line in the glass increased, decreased or stayed the same? Explain. The typical diameter of the aorta is 0.005 m and that of a capillary is 10^-5 m. The average blood speed is 1.0 m/s in the aorta and 0.01 m/s in the capillaries. Assuming that all the blood that flows through the aorta must flow through the capillaries (in other words, the...
