Need Help? Solution to Coin on a Bench Problem

AI Thread Summary

To solve the problem of a coin projected at 6 m/s on a bench with a friction coefficient of 0.7, the frictional force acting on the coin must be calculated first. The frictional force is determined by multiplying the coefficient of friction by the normal force, which equals the weight of the coin. This force will decelerate the coin over time, allowing the calculation of its speed after 0.3 seconds using the equation for motion under constant acceleration. After applying these principles, the final speed of the coin can be determined. This approach provides a clear pathway to finding the solution to the problem.

Completely lost on this question, would be brilliant if someone could offer a solution. Thank you

A coin is projected with a speed of 6m/s along the horizontal surface of a bench. The coefficient of friction between the bench and the coin is 0.7. Modelling the coin as a particle and assuming no air resistance, find the speed of the coin after 0.3 seconds

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...
