A trolley, while going down an inclined plane, has an acceleration of 2 cm s⁻². What will be its velocity 3 s after the start?
Approved Tutor Answer9 Months agoTo find the velocity of the trolley after 3 seconds, we can use the formula for acceleration:
The formula to calculate final velocity (v) when starting from rest is:
v = u + at
Where:
Now, substituting the values into the formula:
v = 0 + (2 cm/s² × 3 s)
Calculating this gives:
v = 6 cm/s
Therefore, the velocity of the trolley after 3 seconds will be 6 cm/s.
