Question
a constant force is applied to an object, causing the object to accelerate at 5.00 m/s^2. A) what I'll the acceleration be if the force is halved? B) What will the acceleration be f the object's mass is halved? C)What will the acceleration be if the force and the object's mass are both halved? D) What will the acceleration be if the force is halved and the object's mass is doubled? a constant force is applied to an object, causing the object to accelerate at 5.00 m/s^2.

F = m a
(A) F is halved then acceleratio also halved.
a = 5/2 = 2.5 m/s^2
(B) if mass is halved then a will be doubled.
a = 2 x 5 = 10 m/s^2
(C) if both are halved then acc. will remain constant.
a = 5 m/s^2
(D) F' -> F/2
m' -> 2m
F' = m' a'
F/2 = 2m a'
a' =F / 4m = a / 4
a = 1.25 m/s^2
