Question

The velocity of a body of man 100g is increased from 5 m/s to 10 m/s in n 5 sec. Calculate the force

Answer 1

Answer:

F=0.1N

Explanation:

Using first eqution of motion, v-u=at

v=10 m/s

u=5m/s

10-5=a5

5=5a

a=1

mass of body=100g=0.1kg

force=0.1*1=0.1 N

Answer 2

Given :

• Mass (m) = 100 g
• Time taken (t) = 5 seconds
• Initial Velocity (u) = 5 m/s
• Final Velocity (v) = 10 m/s

To Find : Force

Answer:

• Force = 0.1 Newton

Explanation:

First of all we have to calculate acceleration of the body.

By using first equation of motion we get :

➝ v = u + at

➝ 10 = 5 + a(5)

➝ 10 - 5 = 5a

➝ 5 = 5a

➝ a = 1 m/s²

Therefore, Acceleration produced by a body is 1 m/s².

Now, let's find the force of body.

➻ Force = mass × Acceleration

➻ Force = 100g × 1 m/s²

➻ Force = 0.1 kg × 1 m/s²

➻ Force = 0.1 Newton

Therefore,Force produced by the body is 0.1 Newton.
