AI Thread Summary
In the discussion, a scenario is presented where a 10 g bullet is fired into a stationary 10 kg wooden block, which then slides 5 cm across a table. Participants express confusion about how to apply the conservation of momentum without given velocities or friction coefficients. The conversation emphasizes the importance of understanding momentum conservation to solve the problem. Ultimately, the problem remains unresolved, with one participant thanking others for their input. The discussion highlights the complexities of physics problems involving momentum and friction.

A 10 g bullet is fired into a 10 kg wood that is at rest on a wood table. The block with the bullet embedded slides 5 cm across the table. What was the speed of the bullet.

Can anyone gimme solution to solve this.
Any help shall be appreciated. I don't understand since no velocities are given. How can one use conservation of momentum law
 
Physics news on Phys.org
Wouldn't you need to know the coefficient of friction or something?
 
Problem solved .
Thankx anyways
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
