Question

Two boxes connected by a light horizontal rope are on a horizontal surface, as shown in the following figure. The coefficient of kinetic friction between each box and the surface is 0.30. One box (box B ) has mass 4.71kg , and the other box (box A ) has mass m . A force F with magnitude 36.9N and direction 53.1? above the horizontal is applied to the 4.71kg box, and both boxes move to the right with an acceleration of a = 1.50m/s2

A:What is the tension T in the rope that connects the boxes

B:What is the mass m of the second box? Use the unrounded intermediate answers to calculate the final one

Explanation / Answer

A) B normal force Fn = mg - Fsin? = 4.71kg * 9.8m/s
