PLEASE ANSWER QUICK!! A student pushes a wagon full of bricks with a constant force across the ground. Which of
the following changes would double the acceleration of the wagon?
A. Removing half of the mass in bricks from the back of the wagon
B. Pulling the wagon over grass instead of concrete
C. Reducing the initial force by half
D. Adding twice as many bricks to the back of the wagon
A. Removing half of the mass in bricks from the back of the wagon
Explanation:
Newton’s Second Law (F = ma) relates mass and acceleration. If the force is constant, to double the acceleration of the wagon (a) you would need to reduce the mass of bricks by ½.
