I need to find the coefficient of the kinetic force and the kinetic force?

AI Thread Summary
To find the coefficient of kinetic friction and the kinetic force for a block accelerating at 2.31 m/sec² with a mass of 0.2485 kg, first calculate the normal force using the equation Fg = mg, resulting in 2.4353 N. Next, apply Newton's second law (F = ma) to establish a relationship for the frictional force in the horizontal direction. By substituting the known values into the equations, you can derive both the coefficient of kinetic friction and the total kinetic force. The process involves using the normal force to solve for the kinetic friction coefficient (µkinetic) and the frictional force (Fk). This method provides a systematic approach to solving the problem.

Homework Statement


a block is accelerating 2.31m/sec^2 horizontally. the block is .2485Kg. what is the coefficient of the kinetic force and the kinetic force?


Homework Equations


Normal force = weight = mg
Fk= kinetic friction coefficient (µkinetic) / normal force (Fnormal)
kinetic friction coefficient (µkinetic) = kinetic friction * normal force (Fnormal)

The Attempt at a Solution


Fg= mg = .2485kg*9.8m/sec^2 = 2.4353N = normal force

Try writing an F=ma equation for the x-direction. This should give you an equation for the frictional force and since you have already solved for the normal force you should be able to solve for both the coefficient of kinetic friction and the total frictional force.

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}...

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...
