A mass of 12 kg is pulled along a horizontal surface by a rope which makes a 15 degree below horizontal as in fig below. The tension in the rope is 80 N. The coefficient of kinetic friction µk between the surface and the mass is 0.38.

5. Draw a free body diagram and include all relevant forces.
6. Find the acceleration of the mass.

1. Show ALL equations, then substitution of numerical values with units.

2. If you have a string of numbers with no preceding equation, sketch, or explanation, you will receive NO CREDIT even if it leads to the correct answer.

3. Make sure all symbols used are clearly identified on your sketch. BOX each required answer. Show work in a Logical Order – Don’t jump around.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
