Question
A fish swimming in a horizontal plane has velocity v, = (4.00 î + 1.00 j) m/s at a point in the ocean where the position relative to a certain rock is r = (12.0 î - 2.20 j) m. After the fish swims with constant acceleration for 15.0 s, its velocity is V = (25.0 î - 3.00 j) m/s.
(a) What are the components of the acceleration of the fish?
ax
m/s2
ay =
m/s2
(b) What is the direction of its acceleration with respect to unit vector î?
° counterclockwise from the +x-axis
(c) If the fish maintains constant acceleration, where is it at t = 30.0 s?
y =
In what direction is it moving?
o counterclockwise from the +x-axis
