A child blows a leaf from rest straight up in the air. The leaf has a constant upward acceleration of magnitude 1.0 ms21.0\,\dfrac{\text m}{\text s^2}1.0s2m1, point, 0, start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction. How much time does it take the leaf to displace 1.0 m1.0\,\text m1.0m1, point, 0, start text, m, end text upwards?
Round the answer to two significant digits.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

your answer is, orbit around the nucleus

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.
