An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ

(t) = a + bt2 – ct3 where a = 0.3 rad, b = 0.85 rad/s2 and c = 0.035 rad/s3

I found a missing question online. <span>What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
</span>A: \theta(0)=a\\&#10;B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c
<span>Our angular displacement is:
</span>\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad<span>

The sum of three consecutive numbers is 243. What is the third number?
marishachu [46]
Three consecutive numbers can be written as x, x+1, and x+2, but they also can be written x, x-1, and x-2 where x is the biggest number.

sum means adding... so

x + x - 1 + x - 2 = 243
combine like terms and solve for x!
