PLEASE HELP ! 1) Carrie pulls a 41.5 kg bin across the floor of her garage using a rope that is attached to the bin. She pulls with a force of 138 N, at an angle of 28.0° above horizontal. The coefficient of kinetic friction between the floor and the box is 0.290. What is the acceleration of the box?

2) Alistair places a 6.40 kg block on an inclined plane that is 23° above the horizontal. The block starts from rest, and in 2.20 seconds, travels 1.40 m. What is the force of friction on the block?
