Question
A trolley, while going down an inclined plane, has an acceleration of 2 \text{ cm s}^{-2}. What will be its velocity 3 \text{ s} after the start?
Answer
Given:
Initial velocity (u) = 0 (starts from rest)
Acceleration (a) = 2 \text{ cm/s}^2
Time (t) = 3 \text{ s}
Formula:
v = u + at
Calculation:
v = 0 + (2 \times 3)v = 6 \text{ cm/s}
Answer: The velocity will be 6 \text{ cm/s}.
