- Homework Statement
- The following information must be considered: the total mass of the cars and riders is 5225 kg. The train leaves the station at 4.5 m/s and it reaches a speed of 8.0 m/s at the top of the first hill. It takes 16.0 seconds to reach the top. The first hill (on the upwards and the downward side) is angled at 38o. The specific heat capacity of brass and the coefficient of linear expansion of steel are 376 J/kgoC and 12 x 10-6 oC-1, respectively. On the day of analysis, the air temperature is 30.oC. We will also assume that the station track is at ground level. In order to determine the length of track, use a piece of string and the vertical scale outlined on the graph.

With what speed would it reach the bottom of the first hill?

How long will it take for the camera to reach the ground?

- Relevant Equations
- Any kinematic formulas, Froce formulas and [work, power and energy formulas]

specific formulas were not given with this question.

I tried finding the distance but I later on got confused.
