Question

An object starting from rest attains a velocity of 10 m/s in 2 seconds. Calculate

its acceleration​

Answer 1

Answer:

• 5m/s² is the required Acceleration.

Explanation:

Given:-

• Initial velocity ,u = 0m/s
• Final Velocity ,v = 10m/s
• Time taken,t = 2

To Find:-

• Acceleration ,a

Solution:-

We have to calculate the acceleration of the object.

As we know that acceleration is defined as the rate of change of velocity at per unit time.

• a = v-u/t

where,

• a denote acceleration
• v denote final velocity
• u denote initial velocity
• t denote time taken

substitute the value we get

→ a = 10-0/2

→ a = 10/2

→ a = 5m/s²

• Hence, the acceleration of the object is 5m/s².

Answer 2

Answer:

Given :-

• Initial velocity = 0 m/s
• Time taken = 2 sec
• Final velocity = 10 m/s

To Find :-

Acceleration

Solution :-

As we know that

$\huge \bf{A = \dfrac{v-u}{t}}$

A is the Acceleration

V is the Final Velocity

U is the Initial Velocity

T is the Time

$\sf \implies \: A = \dfrac{10 - 0}{2}$

$\sf \implies \: A = \cancel \dfrac{10}{2}$

$\frak \red{A \: = 5 \: {ms}^{ - 1}}$
