Aboy is pushing forward on a crate with a force of 100 newtons. the reaction force is
1.the crate pushing back on the boy with a force of 100 newtons.
2.the crate moving forward at a constant rate.
3.the crate remaining at rest with a weight of 100 newtons.
4.the crate accelerating 10 m/s2 forward.

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

14. a body is projected with velocity vi from a.at the same time another body is projectedvertically upwards from point b withvelocity v2 lies vertically below the highestpoint. both the bodies collide thenv2÷v1is

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
