A trolley while going down on an inclined plane has an acceleration of 2cms^-2.What will be its velocity after 2s of the start?

Answer 1

Answer:Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.

Answer 2

Answer:

Initial velocity, u = 0 m/s

Acceleration (a) = 2 cm/s2 = 0.02 m/s2

Time (t) = 3 s

Final velocity, v = ?

We know that, v = u + at

Therefore, v = 0 + 0.02 × 3 m/s ⇒ v = 0.06 m/s
