Question

The chart below represents the change in velocity for four different trains. Change in Velocity for four different trains, Train, Initial Velocity, Final Velocity, W, 60, 91, X, 39, 68, Y, 42, 70, Z, 65, 94 If it took 5.38 s for each train to reach the final velocity, which train had the smallest acceleration?

Answer 1

Step-by-step explanation:

Acceleration = (final velocity - initial velocity) / time

Acceleration of W = ( 91 - 60 ) / 5.38 = 5.76 m /s²

Acceleration of X = ( 68 - 39 ) / 5.38 = 5.39 m /s²

Acceleration of Y = ( 70 - 42 ) / 5.38 = 5.20 m /s²

Acceleration of W = ( 94 - 65 ) / 5.38 = 5.39 m /s²

So Train Y is the smallest acceleration.
