Answer:
F = 0.0545 N
Explanation:
Let's use Newton's second law for rotational movement
τ = I α
The moment of inertia for a bar supported by some ends is
I = 1/3 m L²
Torque is
τ = F L
Let's replace
F L = 1/3 m L² α
F = 1/3 m L α
Let's reduce angular acceleration to SI units
Alf = 26º / s² (π rad / 180º) = 0.454 rad / s²
Let's calculate
F = 1/3 0.5 0.72 0.454
F = 0.0545 N
Given:
Dy= 20 m
Vi = 5.0 m/s horizontally
A=9.81 m/s^2
Find:
Horizontal displacement
Solution:
D=ViT+(1/2)AT^2
Dy=(1/2)AT^2
T^2=Dy/(1/2)A
T=sqrt(Dy/(1/2)A)
T=sqrt(20/4.905)
T=2.0s
Dx=ViT
Dx=(5.0)(2.0)
Dx=10. meters
Answer:
a 30 units of corn and 30 units of wheat.
Explanation:
Initially freedonia has 5 workers producing 30 units of of corn (6 units per worker) and another 5 workers producing 10 units of wheat (2 units per worker)
With the trade agreed between the two countries Freedonia can have all of it's 10 workers producing corn, thereby producing 60 units of corn
30 of these are traded for 30 units of wheat therefore allowing the country to consume 30 units of each product.
1). The little projectile is affected by friction all the way through the block.
Friction robs some kinetic energy.
2). The block is affected by friction as it scrapes along the top of the post.
Friction robs some kinetic energy.
3). The block is also affected by friction with the air (air resistance) as it
falls to the ground. Friction robs some kinetic energy.
