Answer:
It takes 3 seconds over the interval [0,3]
Step-by-step explanation:
To find when the roller coaster reaches the ground, find when d=0.
To solve divide each term by 16 and factor:
Solve for t by setting each factor to 0.
t-3=0 so t=3
t+3=0 so t=-3
This means the car is in the air from 0 to 3 second.
I forgot about this one!! I lbew but I lost it!! Sorry :(
The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.
We know that,
Linear velocity = r x Angular Velocity
where r is the radius.
So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.
So, the correct answer is option C
