an object starts from rest and uniformly accelerates at a rate of 1.25 m/s2 for 7.0 seconds. (a) what is the objects displacement during this 7-second time period? (b) what is the objects final velocity? (c) How Many seconds does it the the object to have a displacement of 22 meters?

grav potential energy

a is the best answer your welcome

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.
