A constant force is applied to an object, causing the object to accelerate at 6.00 m/s^2. What will the acceleration be if:
a.The force and the object's mass are both doubled?
b.The force is doubled and the object's mass is halved?

F = ma,
a = f/m,

a. a = 2f/2m = f/m = no change = 6.00
m/s^2.

b. a = 2f/0.5m = 4 + f/m =4 * 6 = 24
m/s^2.
