The velocity of the canoe is 1.7 m/s.
<h3>What is momentum?</h3>
Momentum in physics is the products of mass and velocity. Now we have to find momentum with the formula; p = mv
a) Initial momentum = (15)8 m/s + 135 = 255 Kgms-1
b) Since momentum is conserved, the total momentum after throwing the anchor is still 255 Kgms-1
c) The final velocity of the boat is obtained from;
255 Kgms-1 = (15Kg + 135 Kg) v
v = 255 Kgms-1/(15Kg + 135 Kg)
v = 1.7 m/s

Answer:
19.1 secs
Explanation:
The first step is to calculate the velocity
= 17.4/47.6
= 0.37 m/s
Therefore the time taken for the person to reach the top can be calculated as follows
= 17.4/(0.37+0.541)
= 17.4 / 0.911
= 19.1 secs
Hence the time taken is 19.1 secs
Answer:
Blue light
Explanation:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves.
