Explanation:
F = ma, and a = Δv / Δt.
F = m Δv / Δt
Given: m = 60 kg and Δv = -30 m/s.
a) Δt = 5.0 s
F = (60 kg) (-30 m/s) / (5.0 s)
F = -360 N
b) Δt = 0.50 s
F = (60 kg) (-30 m/s) / (0.50 s)
F = -3600 N
c) Δt = 0.05 s
F = (60 kg) (-30 m/s) / (0.05 s)
F = -36000 N
The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.
You hold a piece of wood in one hand and a piece of iron in the other. Both pieces have the same volume, and you hold them fully under water at the same depth. At the moment you let go of them, which one experiences the greater buoyancy force?<span>

The person's velocity relative to the shore is determined as 6.5 m/s.
<h3>
Velocity of the person</h3>
The velocity of the person is calculated as follows;
V(p/f) = V(p) - V(f)
where;
- V(p/f) is the velocity of the person relative to the ferry
- V(p) is the velocity of the person
- V(f) is velocity of the ferry
1.5 = V(p) - 5
V(p) = 6.5 m/s
Thus, the person's velocity relative to the shore is determined as 6.5 m/s.
