Question

What is the net force to increas the velocity of 5000g mass from 20m/s 40m/s with in 4 sec

Answer 1

Answer:

25 newtons

Explanation:

Given :

• Mass of the object = 5000 grams = 5 kilo grams = m

• Initial velocity of the object = 20 m/s = u

• Final velocity of the object = 40 m/s = v

• Time taken = 4 seconds = t

To find :

• Net force acting on the body

Force = m(v-u)/t

Force = 5(40-20)/4

Force = 5(20)/4

Force = 100/4

Force = 25 Newtons

The force acting on the body is equal to 25 newtons

What is the net Force to Increases the Velocity of 5000g Mass from 20m/s to 40m/s with in 4 sec..

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\implies\tt{Initial\:Velocity(u)=20m/s}$

$\implies\tt{Final\:Velocity(v)=40m/s}$

$\implies\tt{Time\:Taken(t)=4\:sec.}$

$\implies\tt{Mass\:of\:Object=5kg}$

➥Now ,

$\implies\tt{Force=\dfrac{m(v-u)}{t}}$

➥Putting Values : -

$\implies\tt{Force=\dfrac{5(40-20)}{4}}$

$\implies\tt{Force=\dfrac{5(20)}{4}}$

$\implies\tt{Force=\cancel\dfrac{100}{4}}$

$\red\longmapsto\:\large\underline{\boxed{\bf\green{Force}\orange{=}\purple{25\:N}}}$

☛So , the net force on the body is 25 Newton....
