Answer: The correct answer is 3 m/s.
Explanation:
P= W / t
Where,
P= Power
W= Work
t = Time
And,
W= F.S
[F= force]
[S= Displacement]
So,
P = F.S / t
P = F.V
[because Velocity V= S/t]
Now,
V = P / F
[ Velocity of car depends on the Power & Force, not on the thickness of the water layer ]
V1 = 3 m/s
F1 = 1000 N
P1 = 800 kW
So,
V1 = P1 / F1
3 m/s = 800kW / 1000N .....eq.(1)
Now,
V2 = ?
F2 = 500 N
P2 = 400 kW
So,
V2 = P2 / F2
V2 = 400kW / 500N .....eq.(2)
Divide eq.(2) By eq.(1),
V2 / V1 = P2.F1 / P1.F2
V2 / 3 = 400✖️1000➗ 800✖️500
V2 / 3 = 1 m/s
V2 = 3 m/s
