The object in the diagram is acted upon by the two forces shown.
3N--> object<--2N
What is the effect of these forces?
A The object moves to the left with constant speed.
B The object moves to the left with constant acceleration.
C The object moves to the right with constant speed.
D The object moves to the right with constant acceleration.
Answer's D. Just wanna clarify. A resultant force on an object causes it to accelerate then move in a constant speed, or does it cause it to accelerate constantly? :S HELP HELLPPPP

Accelerate constantly.
F = ma
1N = ma
1N/m = a
m is constant, thus a is constant.

ok .. in this case .. it cannot be CONSTANT SPEED because the force acting on a body will INCREASE the speed UNIFORMLY as the force is being applied the bidy moves with a constant acceleration
