Chapter 6, Problem 96E

(a)

To determine

The number of cars in the train.

(b)

To determine

To show: The extra force needed to accelerate the train is about the same for a $0.10{\text{ m/s}}^2$ acceleration or a $1\%$ slope.

(c)

To determine

To show: With $1\%$ slope an extra $2.9\text{ MW}$ power is needed to maintain the $27\text{}\text{m/s}$ speed of the cars.

(d)

To determine

The number of cars the six diesel units can pull up a $1\%$ slope at $27\text{}\text{m/s}$ speed with $2.9\text{ MW}$ power less available.
