Remember Newton's Second Law F = mass * acceleration
mass = 12 kg
acceleration = 4 m/s^2
F = 12 * 4 = 48 N
The answer would be 187.95 kg.m/s.
To get the momentum, all you have to do is multiply the mass of the moving object by the velocity.
p = mv
Where:
P = momentum
m = mass
v = velocity
Not the question is asking what is the total momentum of the football player and uniform. So we need to first get the combined mass of the football player and the uniform.
Mass of football player = 85.0 kg
Mass of the uniform = <u> 4.5 kg</u>
TOTAL MASS 89.5 kg
So now we have the mass. So let us get the momentum of the combined masses.
p = mv
= (89.5kg)(2.1m/s)
= 187.95 kg.m/s
Answer: a) 557.3kN b) 543kN
Explanation:
Buoyant force = weight of water displaced.
Formula for buoyant force = mg×(density of fluid/density of object)
Density of fluid = density of sea water = 1025kg/m³
Mass of the chamber(m) = 54300kg
g = acceleration due to gravity = 10m/s²
Density of chamber = mass/volume
Where volume of sphere = 4/3Πr³
radius = 4.70/2 = 2.35m
Volume = 4/3×Π(2.35)³
Volume = 54.37m³
Density of chamber = 54300/54.37
= 998.7kg/m³
Substituting the values into the formula for buoyant force
Buoyant force= 54300×10×{1025/998.7}
= 557299N
= 557.3kN
b) Tension in the cable = mass of cable × acceleration due to gravity
= 54300×10 = 543000N or 543kN.
