Question

Akash starting from rest acquire a velocity of 20 m per second in 6 second if the mass of the car is 1200 kilogram calculator force

Answer 1

thus the ans is 4000 N.

Answer 2

Given,

Initial velocity ( u ) = 0

Final velocity ( v ) = 20 m/s

Time ( t ) = 6 seconds

Mass = 1,200 kg

Force = ?

We know that,

⇒ Force = Mass × Acceleration

We have already Mass , so we need to find acceleration.

We can find acceleration of a body if one group among these is given :

1. Time , Initial Velocity and Final Velocity.

2. Displacement , Initial velocity and Time.

3. Displacement , Initial velocity and Final velocity.

Fortunately, we have one group among these.

Then , why are we waiting ? Let's do it !

Using formula,

⇒ Acceleration = ( Final velocity - Initial velocity ) Time taken

⇒ a = ( v - u ) / t

⇒ a = [ ( 20 m/s ) - 0 ] / 6 s

⇒ a = ( 20 m/s ) / 6 s

•°• a = ( 20/6 ) m/s²

Now,

⇒ Force = Mass × Acceleration

⇒ Force = ( 1,200 kg ) × ( 20/6 ) m/s²

⇒ Force = ( 200 × 20 ) kg m/s²

⇒ Force = 4,000 kg m/s²

•°• Force = 4,000 N
