Answer:
Explanation:
Consider downward displacement first .
downward displacement h = 38 m .
downward acceleration = g
downward initial velocity u = 0
h = ut + 1/2 g t ²
38 = 0 + 9.8 t ²
t = 1.97 s
During this period , there will be horizontal displacement with initial velocity u = 10 m /s and acceleration a = 1.6 m /s²
s = ut + 1/2 a t²
= 10 x 1.97 + .5 x 1.6 x 1.97²
= 19.7 + 3.10
= 22.8 m
Answer:
The riders are <u>radially</u> accelerating.
Explanation:
The Ferris wheel is making a circular motion. If it is moving with constant velocity, than the acceleration is

towards the center of the wheel.
So, the riders are subject to a constant and radial acceleration, which is called the centripetal acceleration.
