Afelt-covered beanbag is fired into a empty wooden crate that sits on a concrete floor and is open on one side. the beanbag is moving exactly horizontally when it strikes and sticks to the inside wall of the crate, which is lined with velcro. as a result of this impact, the crate slides backwards 0.935 meters along the concrete, which has a coefficient of kinetic friction of \mu_k = 0.480μ k =0.480. the beanbag has a mass of 0.354 kg and the empty crate has a mass of 3.77 kg. calculate the speed of the beanbag vv at the moment it strikes the crate. you may neglect the effect of air resistance.

31.42383 m/s

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

= Coefficient of kinetic friction = 0.48

s = Displacement = 0.935 m

= Mass of bean bag = 0.354 kg

= Mass of empty crate = 3.77 kg

= Speed of the bean bag

= Speed of the crate

Acceleration

From equation of motion

In this system the momentum is conserved

The speed of the bean bag is 31.42383 m/s

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
