A block of mass m1=5.0 kg moves in uniform circular motion with a radius of 3.0m on a frictionless table. The block is connected by a string and a pulley to another block of mass m2 which hangs through a hole in the center of the table, as shown in the figure. If block 1 is moving at a speed of v=2.0 m/s, what is the mass of block 2?

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.
