Get started for freeA constant force is applied to an object, causing the object to accelerate at 10 m/s2. What will the acceleration be if
a. The force is halved?
b. The object’s mass is halved?
c. The force and the object’s mass are both halved?
d. The force is halved and the object’s mass is doubled?
Exercises 25 describe a situation. Identify all forces acting on the object and draw a free-body diagram of the object.
