Which do you think it is?

Answer 2

idk i think its A or B @soprano.h.d0816

Answer 3

@jabez177 do you know?

Answer 4

F=ma = Mass times Acceleration = (kg)( m/s^2) = Newtons

65 kg is mass times 8 m/s^2 is acceleration = ______ N


65-kg runner at 8m/s2

Answer 5

so are yousaying i need to multiply 65 and 8?

Answer 6

That's what I was getting from that.

Answer 7

so itsA!

Answer 8

If you want to find Force (in Newtons)

multiply Mass by Acceleration.

Answer 9
