CALCULATE the acceleration of the Falcon 9 Rocket if it takes 70 seconds from launch to reach supersonic speed = 343 m/s. b) Calculate the theoretical acceleration of a 549,054 kg Falcon-9 Rocket, during launch when the thrust of its engines has a net force of 7.6 x 10^6 N. (Hint: use Newton's 2nd law and solve for acceleration) c) Neglecting wind resistance, DETERMINE the theoretical time in seconds it would take for the rocket to reach supersonic speed? (Hint, use your kinematic equation (final) = (initial) + a*t, solve for t). d) Briefly discuss reasons for the difference between your theoretical and actual accelerations and times to reach supersonic speed.

Suppose Kevin, a 60.0-kg gymnast, climbs a rope. (a) What Is the tension in the rope if he climbs at a constant speed? (b) What is the tension in the rope if he accelerates upward at a rate of 1.50m/s2 ?
A loaded elevator with very worn cables has a total mass of 2200 [kg], and the cables can withstand a maximum tension of 28,000 [N]. Draw the free-body force diagram for the elevator. In terms of the forces on your diagram, what is the net force on the elevator? Apply Newton’s second law to the elevator and find the maximum upward acceleration for the elevator if the cables are not to break. What would be the answer to part (a) if the elevator were on the moon, where g = 1.62 [m/s2]?
2. Next, imagine the rather than sliding down the hill, the skier holds onto a rope that is connected to a tree at the top of the hill, and that the force of the rope holds the skier in place. How would you modify your force diagram now? Hint: The rope is parallel to the surface of the hill. Show that the net force is zero, again by using the parallelogram rule to show that any 2 forces add up to exactly cancel the 3rd force. Note that tension force is always along the direction of the rope but is not drawn equal to the length of the rope. What must be true for an object in equilibrium is that vector sum of the forces in any and every direction must equal zero. Though, we only need to show that along our chosen coordinate axes. Here it is okay to use the "usual" x- and y- directions
