Define the Problem:To understand thermal energy and chemical changes better by building my own train.
Criteria and Limitations—In this section, please list at least three criteria that must be met by your train design. Also include any limitations that could prevent it from getting its cargo to the station.
Criteria Limitations One steam engine Two separate hills One cargo box Missing tracks Stack items across or atop each other Weight
Design Ideas—Pros and Cons:In this section, describe three design ideas you have for your train. List at least one pro (a positive) and one con (a negative) for each design option
Description of Train Design One Wheels first with two springs underneath each wheel, the panda cargo in the middle with the steam engine in the front, and two sets of helium balloons.
Acceleration of the ball is
Explanation:
The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
For the ball in this problem, we have
m = 0.50 kg (mass)
F = 25 N (force)
thereofre, the acceleration of the ball is

I believe the answer greater than
Refractive Index is a ratio of two similar physical quantity which is dimension less
refractive index = sin I / sin r
therefore it doesn't have a unit.
