A 50 kg skydiver jump from a plane that is 400 m in the air. What is the skydivers kinetic energy when they are 100 m from the ground? (Steps:
(1) Solve for initial potential energy, (2) Solve for final potential energy (3)
Calculate the kinetic energy using the mechanical energy equation)
100,000 J
200,000 J
150,000 J

a, c, d, e are all applying about success strategies.

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

technology is the application of the knowledge gained by science.
