Question

a body has initial velocity of is 2 m/s. in 10 seconds it's velocity is 20 m/s. the acceleration of the body is​

Answer 1

Required Answer :

The acceleration of the body = 1.8 m/s²

Explanation :

Here, we are provided with the initial velocity, final velocity and the time taken by the body. And we need to calculate the acceleration of the body. So, in order to get the value of acceleration we will use the first equation of motion.

First equation of motion :

• v = u + at

where,

• v denotes the final velocity
• u denoted Initial velocity
• a denotes the acceleration
• t denotes the time taken

Solution :

We have :

• Initial velocity of the body = 2 m/s
• Time taken by the body = 10 seconds
• Final velocity of the body = 20 m/s

Need to find :

• Acceleration of the body

Required Soultion :

Using first equation of motion,

→ v = u + at

Substituting the given values :

→ 20 = 2 + (a)(10)

→ 20 - 2 = 10a

→ 18 = 10a

→ 18/10 = a

→ 1.8 = a

Therefore, the acceleration of the body = 1.8 m/s²

Answer 2

Answer:

$\underline{\purple{\ddot{\Mathsdude}}}$

Given:-

• Inital velocity of the body = 2m/s
• Time =10sec
• Final velocity of the body = 20m/s.

To prove :-

• Acceleration of the body

Proof:-

• By using the formula of
• v=u+at(equations of motion)

Now applying the values ,

• 20=2+(a)(10)
• 20-2=10a
• 18 =10a
• 18/10=a
• 1.8=a.

Hope it helps u mate .

Thank you .
