An object in space is initially stationary relative to the earth. then, a force begins acting on the object, starting with a force of 0 n, and increasing at a uniform rate until the magnitude of the force is 38 n after the force has acted for 10 s. the body has a mass of 15 kg. what is the speed of the object at 10 s?

answer: decibel

explanation:

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.
