Answer:
80 m
Explanation:
From the question,
Power(P) = Force(F) × Velocity (V)
P = FV..................... Equation 1
V = P/F.................... Equation 2
Given: P = 4.0×10³ W, F = 8.0×10² N.
Substitute into equation 2
V = 4.0×10³/(8.0×10²)
V = 5 m/s.
Applying,
S = Vt............................ Equation 3
Where S = distance move by the boat, t = time.
Given: t = 16 s, V = 5 m/s
Substitute into equation 3
s = 16(5)
s = 80 m.
Hence the distance moved by the boat is 80 m
