Applying a net force to an object causes it to accelerate with a.=8.0 m/s2. What will the acceleration a2 (in m/$2) of the object be if the mass is doubled 4.0 What will the acceleration a4 (in m/$2) of the object be if the net force is halved and the mass is doubled? Choose... What will the acceleration a, (in m/$2) of the object be if the net force is halved? Choose... What will the acceleration a3 (in m/$2) of the object be if the net force is halved and the mass is halved? Choose
