Question

how much work is needed to be done on a ball of mass 50 gram to give it a momentum of 5 kg ms -1
Please explain...​

Answer 1

Answer:

I think that answer should be 5 Joule...

Explanation:

Hi dear...

...

Hope my explanation may help u...

Given that,

Mass =50 gms = 50/1000 kg =0.05 kg

Then, force =m×(v-u)/t

so putting values... m=0.05 kg.

0.05 ×(v-u) /t =force...

MOMENTUM = m×(v-u)

so... 0.05×(v-u) =5

(v-u) =100

force = MA

=M×(v-u) /t =( 0.05×100)/t

=5/t

time =t is in 1 second... so force is 5/1 =5 .... Hope it might help u.... please mark it brainliest answer
