Answer:
866.92 N
Explanation:
mass of shark, m = 92 kg
density, d = 1040 kg/m^3
Volume, V = mass / density
V = 92 / 1040 = 0.08846 kg/m^3
The lift force is the buoyant force acting on the shark is
Lift force = Volume x density of water x g
Lift force = 0.08846 x 1000 x 9.8
Lift force = 866.92 N
Thus, the lift force is 866.92 N.
Answer: energy=mc^2 is the answer
Answer:
≈147.86 (m.)
Explanation:
1) if the acceleration is a=(V-V₀)/t, where V₀ - initial velocity (25), V - final velocity (2), t - elapsed time, then
t=(V-V₀)/a=23/2.1 (sec.);
2) the required distance can be calculated according to the formula:
S=V₀t+0.5(at²), where V₀=25; t=23/2.1; a= -2.1;
3)
Answer:
.98m
Explanation:
Vf=Vi+2at
(V F)^2+2 ( change in distance )
X f= i ( change in V & T )
