The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. in a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. the toothpick mass was 0.1 g, its speed before entering the branch was 227 m/s, and its penetration depth was 18 mm. if its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick?

143.1361 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

m = Mass

Equation of motion

Force

F = ma

The  magnitude of the force of the branch on the toothpick is 143.1361 N

where's the following? you gotta add it to know what the choices are

explanation:

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.
