Question

calculate the time needed for the net force of 5N change the velocity of 10kg mass by 2m/s.

Answer 1

we know
$force = \frac{change \: in \: momentum}{time}$
$5 = \frac{m(v2 - v1)}{t}$
therefore t = 4s

Answer 2

Hey brainly user!

Here is your answer

Given that

F=5N

m=10kg

change in velocity (V-U) =2m/s

F=ma

=m(v-u) /t

5=10(2)/t

t=4 sec
