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

double the distance = divide strength by 4

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
