Question

A trolley while going down an inclined plane has an acceleration of 2 cm per second square what will be its velocity 3 second after start?
with full steps pls solve it fast

Answer 1

by using the first equation of motion
v=u+at
v=0+0.02*3
v=0.06m per sec

Answer 2

Answer:

Initial Velocity of the trolley, u= 0 cms-1

Acceleration, a= 2 cm s-2

Time, t= 3 s

It is known that final velocity, v= u + at

= 0 + 2*3 cms-1

= 6 cms

Therefore, the velocity of train after 3 seconds is 6 cms-1
