Question

 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?​

Answer 1

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

✎Given, initial velocity (u) = 0 (the trolley begins from the rest position)

✎Acceleration (a) = 0.02 ms-2

✎Time (t) = 3s

As per the first motion equation, v=u+at

Therefore, terminal velocity of the trolley (v) = 0 + (0.02 ms-2)(3s)= 0.06 ms-2

Therefore, the velocity of the trolley after 3 seconds will be 6 cm.s-2✓✓

Answer 2

Explanation:

The velocity of the trolley at 3 sec is 0.06m/s
