<span>As we Know
ω=v/r
I2 = m*R² = 1.5*0.35² = 0.18375 kgâ™m²
I = Is + I2 = 4.28375 kgâ™m²
w = L/I = (v*R*m)/I = (2.8*0.35*1.5)/4.28375 = 0.343 rad/sec
So the answer is 0.343 rd/sec</span>
Answer:
15.1 N
Explanation:
mass of block (m) = 4 kg
angle of inclination = 36 degrees
applied force (P) = 31 N
acceleration due to gravity (g) = 9.8 m/s^{2}
since the block is moving at a constant speed, it means the acceleration is 0 and therefore the summation of all the forces acting on the body is 0
therefore
P - f - mgsinθ = 0
where
- P = applied force
- f = frictional force
- m = mass
- g = acceleration due to gravity
when P = 31 N and the block is pushed upward
31 - f - (4 x 9.8 x sin 36) = 0
f = 7.96 N
now that we have the value of the frictional force we can find P required to lower the block, our equation becomes p + f - mgsinθ = 0 since the block is to be lowered
P + f - mgsinθ = 0
P = mgsinθ - f
P = (4 x 9.8 x sin 36) - 7.96 = 15.1 N
Answer:
The resultant vector is 
.
Explanation:
First, each vector is determined in terms of absolute coordinates:
6-meter vector with direction: 30º north of east.
4-meter vector with direction: 30º east of north.
The resultant vector is obtaining by sum of components:
The resultant vector is .
