Part A
The kinematic equation x = x0 + V0t + 1/2at2 can be used:
Part A Answer
The equation includes acceleration, so option A is wrong. Option C is wrong because the equation only includes constant acceleration, ‘a’. Since choices A and C are wrong, choice D is also wrong. Option B is correct, though, because F = ma and the equation includes ‘a’. As long as the force is constant, acceleration will also be constant. Therefore:
Only with constant forces.
