B. Natasha Romanoff, the Black WidowTM, rushes to save her friend. From an open window, she catches him with a rope. His body slows to a complete stop in exactly 2.15 seconds.
What is the average force acting on his body during that time?

b.transmitters send radio waves, and receivers capture radio waves.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

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
