The coefficient of static friction between the block and the inclined plane is 0.4 and 0=25º. The block is placed on the inclined plane. The block will:
A not move
B. start moving down the incline and then stop before it reaches the bottom of the incline
C. start moving down the incline and continue to increase its velocity
D. start moving and increase its acceleration until it reaches the bottom of the incline
E. start moving and then its acceleration will decrease
F
3 kg
5 kg

the answer is to check all of them! they all apply well at least i think so!

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
