Question

15. A trolley while going down on inclined plane has an acceleration of 2m/s2 . What will be the velocity 5 seconds after start?
​

Answer 1

Answer:

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

Acceleration, a=2cms

−2

=0.02m/s

2

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..

Answer 2

$\huge\fbox\green{☑Verified Answer:-}$

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

Acceleration, a = 2−²cm = 0.02m/s²

Time t = 5S

As per 1st law of motion,

v = u + at

Here V means velocity of a trolley after 5s

V = 0 + 0.02 × 5

= 0.1m/s.

∴ = 0.1m/s..
