Respuesta :
acceleration = (final velocity-initial velocity)/time
5 = (v-0)/20
v = 100m/s
5 = (v-0)/20
v = 100m/s
Answer:
Velocity, v = 100 m/s
Explanation:
It is given that,
Initial speed of the train, u = 0
Acceleration of the train, [tex]a=5\ m/s^2[/tex]
Let v is the velocity of the train at the end of 20 seconds, t = 20 s
Using the equation of kinematics as :
v = u + a × t
v = a × t
v = 5 × 20
v = 100 m/s
So, the velocity of the train after 20 s is 100 meters. Hence, this is the required solution.
