Question

Vanessa is riding a drop ride at a theme park. If Vanessa free falls from rest for 2.60 seconds, how far does she fall? Gravity accelerates her at 9.80m/2^2

Answer 1

Answer:

People are wild about amusement parks. Each day, we flock by the millions to the nearest park, paying a sizable hunk of money to wait in long lines for a short 60-second ride on our favorite roller coaster. The thought prompts one to consider what is it about a roller coaster ride that provides such widespread excitement among so many of us and such dreadful fear in the rest? Is our excitement about coasters due to their high speeds? Absolutely not! In fact, it would be foolish to spend so much time and money to ride a selection of roller coasters if it were for reasons of speed. It is more than likely that most of us sustain higher speeds on our ride along the interstate highway on the way to the amusement park than we do once we enter the park. The thrill of roller coasters is not due to their speed, but rather due to their accelerations and to the feelings of weightlessness and weightiness that they produce. Roller coasters thrill us because of their ability to accelerate us downward one moment and upwards the next; leftwards one moment and rightwards the next. Roller coasters are about acceleration; that's what makes them thrilling. And in this part of Lesson 2, we will focus on the centripetal acceleration experienced by riders within the circular-shaped sections of a roller coaster track. These sections include the clothoid loops (that we will approximate as a circle), the sharp 180-degree banked turns, and the small dips and hills found along otherwise straight sections of the track.

Answer 2

Answer:-

• Time=t=2.6s
• acceleration due to gravity=g=9.8m/s^2
• Distance=s=?

We know that

$\boxed{\sf s=\dfrac{1}{2}gt^2}$

$\\ \rm\longmapsto s=\dfrac{1}{2}\times9.8\times (2.6)^2$

$\\ \rm\longmapsto s= 4.8\times 6.7$

$\\ \rm\longmapsto s=32.4m$
