Question

tell the above question i will mark u as brainlist.​

Answer 1

Answer:

you put extra mass or lessen does not matte rbut if driving force is lessened then Acceleration also will decrease...

Acceleration mean increasing speed...

but here driving force is halved so it will decrease

Answer 2

Answer:

see ..

in simple word this is one-half of the original

origin of the acceleration a=F/M (f=ma)

truck of the mass M is the loaded with a mass M and hence the total mass is 2m.

now the driving forces is also reduced to half .

Thus,M' =2M' ,F'=F/2.

acceleration a' = F/2 / 2M

or a' =1/4a

acceleration becomes one-half of the original.

i hope you understand.
