Question Question 3
A trolley, while going down an inclined plane, has an acceleration of 2 cms-2. What will be its velocity 3 s after the start?
Given,
Initial velocity (u) = 0
Acceleration (a) = 2 cms-2
Time (t) = 3s
According to the first equation of motion,
v = u + at
Substituting we get,
v = 0 + (2 x 3) = 6 cms-1
Hence, velocity of the trolley after 3 seconds will be 6 cms-1
