What will be the change in velocity of a 850kg car if a force of 50,000 N is applies to it for 0.5 seconds?

29.412m/s

Explanation:

where F= force, m= mass, and a=acceleration

we also know that,

a = Δv / t where Δv = change in velocity and t = time

thus F = m ( Δv / t)

Δv

29.412m/s=Δv

the body's situation won't change the forces are equal opposit and on the same body

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
