Leaders who will direct everyone else and make sure everyone is safe.

Which of the following commands is used to list the names of all the variables in the data set? 

Which of these is the file format for log files that can only be read by Stata? 

A mass is being pulled up the incline by a force F with constant speed. The incline is angled at 25o. The interface of the mass/incline has a coefficient of kinetic friction of 0.280. If the mass is 10.0 kg and was pulled for 3.20 meters up the incline, how much work was done by the force F? Assume F is directed parallel to the incline. Report to three significant digits.

A mass is pulled by two forces. The first force has magnitude of 100 N and is directed 300 above the positive x-axis. The second force has a magnitude of 100 N and is directed 300 below the positive x-axis. If the mass of the object is 30.0 kg, calculate the velocity of the mass after the mass is displaced 10.0 m. Assume the initial velocity of the mass was zero at t = 0 s and ignore friction. Answer to two significant digits.

A particle of mass 1.0 kg is moving along the x-axis with a speed of 3.0 m/s. It then collides with a spring and compresses 0.23 m before coming to a rest. Calculate the spring constant of the spring. Just two significant digits.

After a displacement of 54.0 m along the x-axis during a time interval of 0.780 s, a particle went from some initial velocity (not zero) to some final velocity of 25.0 m/s. If the particle was subjected to constant acceleration within this time interval, calculate the particle’s initial velocity. Give three significant digits (be careful with rounding!)
