Momentum is the product of mass x velocity.
p = mv
Where: p = momentum
m = mass
v = velocity
Now you can answer your question by finding the momentum of each:
p = mv
p(w) = 12 x 5 = 60
p(x) = 15 x 8 = 120
p(y) = 18 x 2 = 36
p(z) = 28 x 10 = 280
With that you can now arrange them in ascending order (least to greatest):
Y < W < X < Z
Your answer is D.
Answer:
1) The force per egg caused by the weight of the block is 17.15 N
2)
Explanation:
<u>Pressure</u>
The pressure is computed as the force acting upon a surface divided by the area of the surface
:
The weight of an object of mass m is:
W = mg
Where g is the gravitational acceleration of
The cement block has a mass of m=14 kg, thus its weight is:
W = 14*9.8
W = 137.2 N
1) This weight is evenly distributed over the 8 eggs, thus the force per egg is:
F = 137.2 N/8= 17.15 N
The force per egg caused by the weight of the block is 17.15 N
2) It's given the pressure on each egg as and we know the force acting on each one is F=17.15 N. To find the contact area we solve the formula of the pressure for A:
