Answer:
![\theta = 22.29](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2022.29)
Explanation:
Taking summation of force at perpendicular to the plane
![\sum F_p = 0](https://tex.z-dn.net/?f=%5Csum%20F_p%20%3D%200)
![2N_A +2N_B -mgcos\theta = 0](https://tex.z-dn.net/?f=2N_A%20%2B2N_B%20-mgcos%5Ctheta%20%3D%200)
![N_A +N_B - mgcos\theta = 0](https://tex.z-dn.net/?f=N_A%20%2BN_B%20-%20mgcos%5Ctheta%20%3D%200%3C%2Fp%3E%3Cp%3E)
![N_A +N_B = mgcos\theta](https://tex.z-dn.net/?f=N_A%20%2BN_B%20%3D%20mgcos%5Ctheta)
Taking summation along the plane, therefore we have
![\sum Fa = 0](https://tex.z-dn.net/?f=%5Csum%20Fa%20%3D%200)
![\mu N_A+\mu N_B - mgsin\theta = 0](https://tex.z-dn.net/?f=%5Cmu%20N_A%2B%5Cmu%20N_B%20-%20mgsin%5Ctheta%20%3D%200)
from equation 1 and 2 we have
![\mu =\frac{sin\theta}{cos\theta}](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7Bsin%5Ctheta%7D%7Bcos%5Ctheta%7D)
![\mu = 0.41](https://tex.z-dn.net/?f=%5Cmu%20%3D%200.41)
![\mu = tan\theta](https://tex.z-dn.net/?f=%5Cmu%20%3D%20tan%5Ctheta%3C%2Fp%3E%3Cp%3E)
![\theta = tan^{-}\mu](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-%7D%5Cmu)
![\theta = 22.29](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2022.29)
Answer:2800000j
Explanation:
For us to know the kinetic energy of the vehicle,
Where m is the mass
And v is the velocity
Then, K.E=1/2mv^2
While, K.E=1/2×3500×40^2
Therefore, our answer will now be
K.E=2800000j
Answer: 17cm.
Explanation:
The equation you're using is:
Δd = df - di
Which means the change in position is equal to the final position minus the starting position. In this case that works out to 20cm - 3cm = 17cm. We're only interested in how much the snail moved, not how long it took to move, so even though they give a time it actually doesn't matter for this question.
