A 0.42 kg soccer ball is initially moving at 2 m/s. A soccer player kicks the ball, exerting a constant 40 N force in the same direction as the ball's motion. Over what distance must her foot be in contact with the ball to increase the ball's speed to 6 m/s? A block of ice with mass 2 kg slides down a frictionless inclined plane that slopes at an angle of 37° below the horizontal. If the block of ice starts from rest, what is its speed after moving a distance of 0.75?

it is easily magnetized.

thermal energy is the answer

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.
