a train is accelerating at a rate of 3m/s2. if its initial velocity is 30m/s what is its velocity after 60 seconds?
To find the velocity of the train after 60 seconds, we can use the following equation:
v = u + at
where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
u = 30 m/s
a = 3 m/s^2
t = 60 seconds
Plugging in the values, we have:
v = 30 + (3)(60)
v = 30 + 180
v = 210 m/s
Therefore, the velocity of the train after 60 seconds is 210 m/s.
