Problema Solution
A train is accelertating at a rate of 2 m/s . If its initial velocity is 20 m/s , what is its velocity after 30 seconds
Answer provided by our tutors
Formula for velocity as a function of initial velocity, acceleration and time.
v = v0 + at
v0 = 20 m/s initial velocity
v = velocity
a = 2 m/s^2 acceleration
t = 30 sec time
v = 20 + 2*30
v = 80 m/s
after 30 seconds the velocity is 80 m/s.
