Question

a trolley while going down an inclined plane has an acceleration of 2 centimetre per second square what will be its velocity 3 seconds after the start

Answer 1

Speed of trolley = 2cm / sec
so , in 3 sec After the start will be 2 cm × 3 sec = 6cm / sec

Answer 2

Answer:

Given:

Given:a = 2cm/s² = 0.02m/s²

Given:a = 2cm/s² = 0.02m/s²u = 0m/s

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secs

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:final velocity, v = ?

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:final velocity, v = ?Solution:

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:final velocity, v = ?Solution:v = u + at

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:final velocity, v = ?Solution:v = u + atv = 0 + 0.02(3)

Given:a = 2cm/s² = 0.02m/s²u = 0m/st = 3secsTo find:final velocity, v = ?Solution:v = u + atv = 0 + 0.02(3)v = 0.06m/s
