6. rank the following in terms of increasing kinetic energy: a. a 1200 kg car going 15 m/s b. a 10,000 kg train car at rest c. a 15 kg meteor going at a speed of 1000 m/s d. a 100 kg person running at 5 m/s

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
