7. A force causes a mass of 4 kg to have an acceleration of 8 m/s2. Suppose something causes the (1 point) mass to be one-quarter of its original amount. What will happen to the acceleration if the amount of force used remains the same? It will decrease to 2 m/s2 It will remain the same. It will increase to 32 m/s2. It will increase to 16 m/s2 8. What is the force required to propel a 2.00 kg object...
