Question

2) A trolley while going down an inclined plane, has an acceleration of 2cm/s². What will be its velocity 3s after the start?

Answer 1

$\huge\mathfrak{\underline{\underline{Solution:-}}}$

A = 2 cm ${s}^{-2}$

Initial velocity, u = 0

Final velocity , v = ?

Time , t = 3s

$\underline\textsf{Using\:1st\:equation\:of\:motion:-}$

v = u + at

v = 0 + 3 × 2

v = 6 m/s.

Answer 2

Answer:

Solution:-

v = u +at

v = 0 + 3 * 2

v = 6
