SSM REASONING The speed of the fish at any time t is given by v = v x2 + v 2y , where
vx and vy are the x and y components of the velocity at that instant. Since the horizontal
motion of the fish has zero acceleration, vx = v0 x for all times t. Since

28. REASONING The drawing at the right shows the
velocity vector v of the water at a point below the top
of the falls. The components of the velocity are also
shown. The angle is given by tan = v y / vx , so that

48. REASONING Since car A is moving faster, it will eventually catch up with car B. Each car
is traveling at a constant velocity, so the time t it takes for A to catch up with B is equal to
the displacement between the two cars (x = +186 m) divided by the

= tan 1
where x is the horizontal displacement of the flare.

Since a x = 0 , it follows that
x = (v0 cos 30.0)t . The flight time t is determined by the vertical motion. In particular, the

64. REASONING The magnitude and direction of the initial velocity v0 can be obtained using
the Pythagorean theorem and trigonometry, once the x and y components of the initial
velocity v0x and v0y are known. These components can be calculated using Equati
