At least one of the answers above Is NOT Correct. (1 point) Two masses of 2.50 kg each, connected by a string, slide down a ramp making an angle of 43° with the horizontal. The coefficient of kinetic friction between M, and the ramp is 0.34. The coefficient of kinetic friction between M2 and the ramp is 0.10. MI M2 Find the magnitude of the acceleration of the masses. 8.904938958698487 m/s^2 What is the tension in the string? 23.31 N
