The speed of an object is the distance the object covers in a given time. Speed is a scalar quantity, and therefore, the direction of motion is not considered
The length of the train is 1950 feet
Reason:
Given parameters
Length of the tunnel, D = 650 feet long
Speed of the train = 100 ft. per second
Time time after which the last car exits the other end = 26 seconds
The length of the train = Required
Solution:
The distance traveled by the train in 26 seconds, d = 100 × 26 = 2,600 feet
∴ The distance traveled by the train in 26 seconds, d = 2,600 feet
The length of the train, L = d - D
L = 2,600 - 650 = 1,950
The length of the train, L = 1950 ft.
