Question

a trolley, while going down an inclined plain has an acceleration of 2cm/s2.
what will be its velocity 3s after the start​

Answer 1

Explanation:

$\huge\fcolorbox{black}{green}{Given}$

• Initial velocity, u = 0 m/s

• Acceleration (a) = 2 cm/s2 = 0.02 m/s2

• Time (t) = 3 s

• Final velocity, v = ?

$\huge\fcolorbox{black}{green}{Formula Used}$

First equation of motion

➣ v = u + at

$\huge\fcolorbox{black}{green}{Solution}$

⇒v = 0 + 0.02 × 3 m/s

⇒ v = 0.06 m/s

Therefore the final velocity of trolley will be 0.06 m/s after start.

Answer 2

Initial velocity, u = 0 m/s

Acceleration (a) = 2 cm/s2 = 0.02 m/s2

Time (t) = 3 s

Final velocity, v = ?

First equation of motion

v = u + at

v = 0 + 0.02 × 3 m/s

v = 0.06 m/s

Therefore the final velocity of trolley will be 0.06 m/s after start.

hope it helps...... ❤️
