Question

A train travels for 3 h, starting from the train station where it picks up the passengers and speeding up to 50 km/h. What is the train's acceleration?​

Answer 1

the acceleration of the train is 16.67 km/h^2.

Explanation:

We can use the following formula to calculate the acceleration of the train:

a = (v_f - v_i) / t

where:

a = acceleration

v_f = final velocity (in this case, 50 km/h)

v_i = initial velocity (in this case, 0 km/h)

t = time (in this case, 3 hours)

Substituting the values into the formula, we get:

a = (50 km/h - 0 km/h) / 3 h

a = 50 km/h / 3 h

a = 16.67 km/h^2

Therefore, the acceleration of the train is 16.67 km/h^2.
