Question
A fisher sets out to check his fishing nets and heads 15 km/h [N] for 0.20 h. After stopping for 0.50h, he travels at 12 km/h [E] for 0.10 h to get to the next set of fishing nets.
a) What is the fisher's displacement to get to the first set of nets?
( I got 3 km [N])
b) What is the fisher's resultant displacement from the dock to the second set of nets?
(I got 3.3 km [20 degrees E of N]
c) What is the average velocity from the dock to the second set of nets?
( I got4.1 km/h [20 degrees E of N]
d) What is the average speed from the dock to the second set of nets?
(I got 5.3 km/h)
e) The fisher returns to the dock. Now what are his resultant displacement and average velocity?
(I'm not sure about this one)
Are the above answers right?
