Appropriate Question :

A body starts from rest and travels with uniform acceleration of 2 m/s², if its velocity is v after making a displacement of 9m . Then find the value of 'v'.

Answer:

6 m/s

Explanation:

As per the provided information in the given question, we have :

  • Initial velocity, u = 0 m/s [Starts from rest]
  • Acceleration, a = 2 m/s²
  • Displacement, s = 9 m

We have been asked to calculate the final velocity, v.

By using the third equation of motion,

v² u² = 2as

  • v denotes final velocity
  • u denotes initial velocity
  • a denotes acceleration
  • s denotes distance/displacement

On substituting values,

→ v² ― (0)² = 2 × 2 × 9

→ v² ― 0 = 36

→ v² = 36

→ v = √36

→ v = 6

Final velocity = 6 m/s

Therefore, the v is 6 m/s.

Answer:

As a result, the v is 6 m/s.

Explanation:

We have the following information based on the information supplied in the given question:

Initial velocity, u = 0 m/s [Starts from rest]

Acceleration, a = 2 m/s²

Displacement, s = 9 m

We've been given the task of calculating the final velocity, v.

By using the third equation of motion,

• v² ― u² = 2as

v denotes final velocity

u denotes initial velocity

a denotes acceleration

s denotes distance/displacement

On substituting values,

→ v² ― (0)² = 2 × 2 × 9

→ v² ― 0 = 36

→ v² = 36

→ v = √36

→ v = 6

→ Final velocity = 6 m/s

Therefore, the v is 6 m/s.
