What are the multiple choice answers?
Explanation:
power output=(1800×10×0.06)/9=120watts
Answer:
w = 0.886 rad / s
Explanation:
Angular and linear variables are related
a = α r
where a is the linear acceleration, α the angular acceleration and r the radius of gyration
α = a / r
the angular velocity we can find it
w² = w₀² + 2 α θ
the initial angular velocity is zero, the angles to be horizontal is
θ = π/ 2 rad
we substitute
w = √ 2 a / r θ
we calculate
w = √ (2 3/12 π/2)
w = 0.886 rad / s
As it is given to us
![P = 6i - 5j + 2k](https://tex.z-dn.net/?f=P%20%3D%206i%20-%205j%20%2B%202k)
![Q = 2i + 2j + 8k](https://tex.z-dn.net/?f=Q%20%3D%202i%20%2B%202j%20%2B%208k)
also it is given that
P - Q + R = 0
so here we can rearrange it to find the value of R
![R = Q - P](https://tex.z-dn.net/?f=R%20%3D%20Q%20-%20P)
so here we have
![R = (2i + 2j + 8k) - (6i - 5j + 2k)](https://tex.z-dn.net/?f=R%20%3D%20%282i%20%2B%202j%20%2B%208k%29%20-%20%286i%20-%205j%20%2B%202k%29)
![R = -4\hat i + 7\hat j + 6\hat k](https://tex.z-dn.net/?f=R%20%3D%20-4%5Chat%20i%20%2B%207%5Chat%20j%20%2B%206%5Chat%20k)
so the vector is given by above equation
