there's the rt angled triangle with alpha (α) as one of the angles and with t as the height of it, and as the answer is also in terms of t I assume it's necessary to do something with this triangle but at the same time the answer only contains one angle, ϑ.

I can't seem to find the proof for the distance between the two parallel lines. Homework Equations : Snells law: μ1sinθ1=μ2sinθ2 Sin (A+B)= sinAcosB + sinBcosA[/B]The Attempt at a Solution : tried using the parallel lines to get a result in terms of the initial angle of incidence ϑ, as the...

But this equation would give (0.5)(m)(v)^2=-(0.5)(k)(x)^2 because Ui=0 and Ki=0 and Uf=1/2kx^2 and Kf=1/2mv^2 , resulting in a negative velocity

the energy of the block giving the velocity of the block after the bullet hits it right? but then what collision formula could be used to find the velocity as the bullet leaves

this would be considered as an inelastic collision where (m1v1) + (m2v2) = (m1+m2)vf also the conservation of energy being (∆K +∆U)=0 i tried using the conservation of energy to find v2 as the variable we are looking for is Vf, the speed the bullet leaves the block, and v2 (velocity of the...
