Explanation / Answer

Initial horizontal velocity = u = 1.4 m/s

t = 0.49s

since the initial vertical velocity = 0 m/s

therefore, vy = uy + gt = 0 + 9.8(0.49) = 4.802 m/s

[The answer you have entered is correct but the system wrongs it because it asked for a magnitude which cannot be a negative value! ]

E]

Magnitude of the book's velocity before it reaches the ground is:

v = [(1.4)2 + (4.802)2]1/2 = 5.002 m/s.
