Answer:
4.64m/s
Explanation:
We can use the formula [ v = √2gh ] to solve for this problem. We know that g is constant acceleration (9.8), and h is height (1.1).
v = √2(9.8)(1.1)
v ≈ 4.64m/s
Best of Luck!

The SI unit of measure for work, as well as
for all other kinds of energy, is the "joule".
1 watt = 1 joule/sec
1800 watts = 1800 joules/sec
(1800 J/sec) x (20 min) x (60 sec/min)
= (1800 x 20 x 60) joules = 2,160,000 joules .
( 2.16 megajoules )
according to PBS learning media on a roller coaster energy changes from potential to kinetic energy and back again many times over the course of a ride kinetic energy is energy that an object has as a result of its motion.
roller coaster system is greatest at the bottom of the largest downhill slope on the track typically at the bottom of the lift Hill
so at the bottom
