Question

A train is accelerating at a rate of 2.0 m/s/s. If it accelerates at this rate for 30

seconds, what is the change of velocity? *

Answer 1

60m/s

Step-by-step explanation:

Given parameters:

Acceleration = 2m/s²

Time = 30s

Unknown:

Change in velocity = ?

Solution:

Acceleration is the rate of change of velocity with time.

Mathematically;

Acceleration =
`(Change in velocity )/(Time )`

Now,

Change in velocity = Acceleration x time

So,

input the parameters and solve;

Change in velocity = 2 x 30 = 60m/s
