Question

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


so in this question why u is 0​

Answer 1

Answer:

u= initial velocity

we are asked to find the velocity after 3 s start

so as it is said as START, u= 0.

V = u+at

V = 0+ 2 × 3

V after 3 s = 6m/s
