Compute all parts of given problem:
Problem: Two boxes connected by a light horizontal rope are on a horizontal surface. The coefficient of kinetic friction between each box and the surface is 0.30. One box (box B) has mass 4.51kg, and the other box (box A) has mass m. A force F with magnitude 36N and direction 53.1 degree above the horizontal is applied to the 4.51kg box, and both boxes move to the right with 1.50m/s2.
Part A: What is the tension T in the rope that connects the boxes?
Part B: What is the mass m of the second box?
Please show complete calculation thank you!
