Question

a truck of mass m is moved under a force f if the truck is then loaded with an object equal to mass of the truck and the driving force is halved ,then how the acceleration change

Answer 1

here we are having m= 2m

force =1/2 n

a =f/m

=1/2×2M

=1/4 m/s2

so accerelation will be 1/4

Answer 2

Answer:

The acceleration will change by 1/4.  

Explanation:

According to the Newton’s law, F = ma (Force = mass X acceleration)

So, Acceleration = Force/mass (a = F/m)

Let’s assume before loading mass the truck = m and force = f

So the acceleration of truck before loading = f/m

After loading mass of truck = 2m

So, after loading driving force will be= 1/2f

Truck Acceleration after loading= 1/2f / 2m = f/4m

Acceleration has been changed after loading by 1/4.
