Need help approaching this question, just started taking physics this year. A train accelerates steadily from 4 ms^-1 to 20ms^-1 in 100s. From its initial and final velocities, calculate the average velocity of the train.

Hello @tombraider5000 !

$\sf \huge Average~Velocity=\frac{Total~Displacement}{Time~Taken}$

abhisar · Answer

STEP 1
Can you calculate the acceleration by using the eqaution v=u+at ?

abhisar · Answer

STEP 2
Now calculate the total displacement by using the equation s=ut+$\sf\frac{1}{2}a\times t^2$

STEP 3
Finally calculate the average velocity
