Question

A trolley, while going down an inclined plane, has an acceleration of 3m s-2. What will be its velocity 4 s after the start?​

Answer 1

Answer:

6m/s

Explanation:

1² second: 3m distance covered

2²second: 3+3

°•° 4second= 6m

Answer 2

Explanation:

Acceleration = 3m/s^2

Initial Velocity = 0m/s^2

Time = 4s

Therefore,

v = u + at

= 0 + (3 × 4)

v = 12m

Hope it helps :)
