Question

a body of mass 10kg is moving with velocity of 5m/s attains of 35m/s in 5 second find the force applied on body to change its velocity​

Answer 1

Answer:

the velocity e of the body will be the max as the the mass of the object is 10 kg as you know when the mass of the object is more then the the velocity of the object will be more

Answer 2

AnswEr :

›»› The force applied on body to change it's velocity is 60 Newton.

Given :

• Mass of a body (m) = 10 kg
• Initial velocity of body (u) = 5 m/s
• Final velocity of body (v) = 35 m/s
• Time taken by body (t) = 5 sec

To Calculate :

• The force applied on body to change its velocity.

How to Calculate?

❒ To calculate the force applied on body to change its velocity firstly we need to find the Acceleration produced or Acceleration of body, after that we will calculate the force applied on body to change its velocity on the basis of conditions given above.

Since, we are provided with the Final velocity, initial velocity and time taken by the body, we can use the first equation of motion to find the Acceleration produced or Acceleration of body.

After calculating the acceleration of body we provided with the Mass and Acceleration of the body, we can use second law of Newton to calculate the force applied on body to change its velocity.

Let's start our calculations...$.$

Calculation :

From first equation of motion

⇒ v = u + at

⇒ 35 = 5 + a * 5

⇒ 35 = 5 + 5a

⇒ 35 - 5 = 5a

⇒ 30 = 5a

⇒ a = 30/5

⇒ a = 6

Now, we have three elements that used in formula, Mass and Acceleration of the body. And we need to find the force applied on body.

• Mass of body (m) = 10 kg
• Acceleration of body (a) = 6 m/s²
• Force applied on body (F) = ?

From second law of Newton

⇛ F = ma

⇛ F = 10 * 6

⇛ F = 60 N

║Hence, The force applied on body to change it's velocity is 60 Newton.║
