3. [-/6 Points] DETAILS MY NOTES A fish swimming in a horizontal plane has velocity v. = (4.00 i + 1.00 j) m/s at a point in the ocean where the position relative to a certain rock is r. = (16.0 1 - 4.20 j) m. After the fish swims with constant acceleration for 17.0 s, its velocity is V = (17.0 i - 6.00 j) m/s. (a) What are the components of the acceleration of the fish? m /s 2 m / s 2 (b) What is the direction of its acceleration with respect to unit vector i? . counterclockwise from the +x-axis (c) If the fish maintains constant acceleration, where is it at t = 24.0 s? X = E y = E In what direction is it moving? . counterclockwise from the +x-axis 4. [-/5 Points] DETAILS MY NOTES A home run is hit in such a way that the baseball just clears a wall 18.0 m high, located 128 m from home plate. The ball is hit at an angle of 33.0 to the horizontal, and air resistance is negligible. (Assume that the ball is hit at a height of 1.0 m above the ground.) (a) Find the initial speed of the ball. m/s (b) Find the time it takes the ball to reach the wall. (c) Find the velocity components of the ball when it reaches the wall. x-component n/s y-component n/s Find the speed of the ball when it reaches the wall. m/s
