For the system below assuming no friction, to double the current value of the system acceleration, you can:
I. Double the value of my
II. Halve the value of mi
III. Halve the value of (m; + m2) by adjusting m, only.

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
