Question

if an object mass 20 kg Has velocity of 10 metre per second then what will its acceleration​

Answer 1

Since the body is moving with constant velocity,v = 10m/s ,

ACCELERATION = ZERO

Answer 2

Given:

An object mass 20 kg Has velocity of 10 metre per second.

To find:

Acceleration of mass ?

Calculation:

Acceleration is defined as :

• $\rm in{s}tantaneous$ rate of change of velocity with respect to time.

Now, the car is having a constant velocity of 10 m/s, which means that the velocity is not changing with time. So, acceleration will be 0 m/s².

$\rm \therefore \: acceleration = \dfrac{\Delta v}{\Delta t}$

$\rm \implies\: acceleration = \dfrac{10 - 10}{\Delta t}$

$\rm \implies\: acceleration = \dfrac{0}{\Delta t}$

$\rm \implies\: acceleration = 0 \: m {s}^{ - 2}$

Hence, acceleration of the mass will be 0 m/s².
