Answer:

20 N

Explanation:

In air, the normal force is equal to the weight.

∑F = ma

N − mg = 0

N = mg

Submerged in water, the normal force is equal to the weight minus the buoyant force:

∑F = ma

B + N − mg = 0

N = mg − B

Plugging in values:

80 N = 100 N − B

B = 20 N

Equation of Motion Problems
barxatty [35]

Answer:

Below in bold.

Explanation:

1. Speed = distance / time

= 100 / 9.84

= 10.16 m/s.

Speed =  200/19.32 = 10.35 m/s.

Speed =  400/43.49 = 9.20 m/s.
