Answer:
Explanation:
Given
Mass of crate is m=574 kg
The crate is raised up to a height of 1.3 m
time taken t=2 s
Work done to raise the crate is equal to the change in its potential energy
The relative pressure at this state is determined as 0.455.
<h3>Initial pressure of the ideal gas </h3>
The pressure of the ideal gas given rise to the relative pressure is calculated as follows;
R.P = P2/P1
P2 = P1(R.P)
P2 = 200 kPa x (3.482)
P2 = 696.4 kPa
<h3>New relative pressure</h3>
R.P = (P3)/(P2)
R.P = (320)/(696.4)
R.P = 0.455
Thus, the relative pressure at this state is determined as 0.455.

Answer:
The slowdown took 2.05 seconds and the roller coaster made a distance 20.5 during that time.
Explanation:
Start with the kinematic equation for velocity. Let v1 and v2 be the initial and the new velocity, respectively. Let s denote the distance made duringthe slowdown. Let m denote the mass of the roller coaster and "a" its acceleration (negative = deceleration). the equation is as follows:
Let us first determine the distance made:
The roller coaster made 20.5 meters during slowing down to 2 m/s. Now calculate the time this took.
It took 2.05 seconds to achieve the slowdown from 18 to 2 m/s
