Question

Please answer all.

The displacement vectors A and B shown in the figure below both have magnitudes of 3.70 m. The direction of vector A is θ = 38.5° (a) Find A B graphically magnitude direction o counterclockwise from the +x axis (b) Find A B graphically magnitude direction o counterclockwise from the +x axis (c) Find B A graphically magnitude direction o counterclockwise from the +x axis (d) Find A 2B graphically magnitude direction o counterclockwise from the +x axis A fish swimming in a horizontal plane has velocity vi = (4.00 Î + 1.00 j) m/s at a point in the ocean where the position relative to a certain rock is ri = (16.0-4.20j) m. After the fish swims with constant acceleration for 19.0 s, its velocity is V (15.0 1-3.00j) m/s. (a) What are the components of the acceleration of the fish? m/s m/s2 (b) What is the direction of its acceleration with respect to unit vector i? o counterclockwise from the +x-axis (c) If the fish maintains constant acceleration, where is it at t28.0 s? In what direction is it moving? o counterclockwise from the +x-axis

Answer 1

This question is based on the concept of
