I just realized this should have been posted in the homework thread, if there is a moderator here, please feel free to move it to the appropriate homework thread for Physics. Thanks!

A 1.2 kg cart slides eastward down a frictionless ramp from a height of 1.8 m and then onto a horizontal surface where it has a head-on elastic collision with a stationary 2.0 kg cart cushioned by an ideal Hooke’s law spring. The maximum compression of the spring during the collision is 2.0 cm...

Ohh I understand how it all works now! Thanks for your time and help

Yes, I do know what static and kinetic friction mean. The type of friction that must be overcome is the force of static friction, as the refrigerator is stationary initially, no? So I already found that which is 245 N. Because Fa = Fs (as I stated before). Fs = Us * Fn = (0.25)(100*9.8)...

Homework Statement The coefficient of kinetic friction between a refrigerator and the floor is 0.20. The mass of the refrigerator is 100.0 kg, and the coefficient of static friction is 0.25. Determine the acceleration when you apply the minimum force needed to get the refrigerator to move...
