Question

A trolley, while going down an inclined plane, has an accleration of 2 cm s$^{–2}$ . what will be its velocity after 3 s after the start ?​

Answer 1

Answer:

Discord lets friends communicate directly via voice, video, or text, and join servers where larger communities can interact together. Gaming is definitely Discord's focus, at one point the service even gave free away PC games to paid subscribers before realizing it couldn't beat Steam

Answer 2

$\huge\underline{\overline{\mid{\bold{\red{Answer ♡}}\mid}}}$

Initial velocity of a trolley, u=0 (at rest)

Acceleration, a=2cms -²

=0.02m/s²

Time t=3S

As per 1st law of motion,

v=u+at

Here V means velocity of a trolley after 3s

V=0+0.02∗3

=0.06m/s.

∴=0.06m/s..
