Answer:
New gravitational force would be: 
Explanation:
Recall the general form of the gravitational force between two objects of masses m1 and m2 separated a distance "d":

which for the 2000 kg trucks becomes:

when we add 1000 kg of bricks to one truck, we get the following unknown force (x) that we need to find:

Now we divide term by term the last equation by the previous one, in order to cancel out common factors to both equation (G, d^2) and get the following equation:

Answer:
KE = incident energy - work function
The maximum KE will be (3 - .6) eV = 2.4 eV
Answer:
3.844 x 10 to the 5th power
