Areckless coyote engineer straps on a pair of ice skates and attaches a rocket capable of producing 5.0 × 10 3 n of thrust to his back. together, the coyote and the rocket have a mass of 120 kg. if the coyote starts at rest on level, frictionless ice and bends over such that the rocket thrust is directed parallel to the ice, what is his final speed if the rocket burns for 5.0 s?

208.33 m/s

Explanation:

t = Time taken

u = Initial velocity = 0

v = Final velocity

a = Acceleration

m = Mass of coyote and the rocket = 120 kg

F = Force of thrust produced by the rockets =

Velocity of the rocket at 5 seconds is 208.33 m/s

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
