Question

A trolley while going down an inclined plane has an acceleration of 2cm per second what will be the velocity 3 seconds after the start

Answer 1

Given:

a = 2cm/s² = 0.02m/s²

u = 0m/s

t = 3secs

To find:

final velocity, v = ?

Solution:

v = u + at

v = 0 + 0.02(3)

v = 0.06m/s

Answer 2

Answer:

v = 6 cm/s = 0.06 m/s

Explanation:

final velocity ,v = ?

initial velocity , u = 0 cm/s

acceleration , a = 2 cm/s^2

time ,t = 3 s

therefore,

v = u + at

v = 0+ 2*3

v = 6 cm/s = 0.06 m/s
