To drag a 75kg log along the ground at constant velocity, you have to pull in it with a horizontal force of 250N. a) what is the resistive force exerted by the ground? b) what horizontal foce must you exert if you want to give the log an acceleration of 2m/s^2?

Why my answer as -75kg as the resistive force exerted by the ground was concidered wrong? As well as 150N as the horizontal force that should be exerted to give the log an acceleration of 2m/s^2 was concidered wrong too.
