1. As shown in the diagram above, a crate of mass 5 kg is initially moving upwards. A rope exerts 33 N of tension upwards on the crate. Calculate the acceleration of the crate.
Enter your answer in meters per second squared and round to the nearest tenth (one decimal). Enter a positive answer for an upward acceleration and a negative answer for a
downward acceleration

2. As shown in the diagram above, a crate of mass 40 kg is pulled by a rope which exerts tension force 141 at an angle of 30 degrees from horizontal. The crate is initially moving to the right but slows down at a rate of 1.5 m/s2. Calculate the magnitude of the force of kinetic friction on the crate. Enter your answer in Newtons and round to the nearest tenth (one decimal).
