Question

a trolley. while going down a inclined plane. has an acceleration of 0.02 m/s. what will be it’s velocity 3s after the start

Answer 1

Answer:

0.06 m/s

Explanation:

Given :

• Initial velocity = u = 0 m/s (starts from rest)

• Time taken = t = 3 seconds

• Acceleration of the trolley = a = 0.02 m/s²

To find:

• Final velocity of the trolley after 3 seconds

Using the first equation of motion :

V=u+at

V=0+0.02×3

V=0.02×3

V=0.06 m/s

The final velocity of the object after start with an acceleration of 0.02 m/s² is equal to 0.06 m/s

Answer 2

Answer:

Explanation:

Correct Question,

A trolley, while going down an inclined plane has an acceleration of 0.02 m/s. What will be its velocity 3s after the start ?

Solution,

Here, we have

Initial velocity of the trolley, u = 0 (As starts from rest)

Acceleration of the trolley, a = 0.02 m/s²

Time taken by the trolley, t = 3 seconds

To Find,

Final velocity of the trolley, v = ?

According to the 1st equation of motion,

We know that,

v = u + at

So, putting all the values, we get

⇒ v = u + at

⇒ v = 0 + 0.02 × 3

⇒ v = 0.02 × 3

⇒ v = 0.06 m/s

Hence, the final velocity of the trolley is 0.06 m/s.
