Question

The velocity of a body is increases from 10 m/s ti 15 m/s in 5seconds calculate its acceleration​

Answer 1

`accelaration = (change \: in \: veloity)/(time) \\ = (15 - 10)/(5) \\ = (5)/(5) \\ = 1 \frac{m}{ {s}^( - 2) }`

Answer 2

Answer: acceleration = 1 m/s²

Concept:

Here, we need to know how to calculate the acceleration of a body.

a = Δv / Δt = (v₂ - v₁) / (t₂ - t₁)

v = velocity

t = time

unit = m/s²

Solve:

Given information

v₁ = 10 m/s

v₂ = 15 m/s

Δt = 5 seconds

Given expression

a = (v₂ - v₁) / (t₂ - t₁)

Substitute values into the expression

a = (15 - 10) / 5

Simplify values in parentheses

a = 5 / 5

Simplify by division

`\boxed{a=1}`

Hope this helps!! :)
