For 2 and 3 use the following:
Vector P: 50 meters @ 110 degrees
Vector Q: 35 meters @ 315 degrees
What is 3P - 3Q?

Dick Rutan, the man attempting to fly around the world in a balloon, is floating due east at 18 km/hr. One hour later he has turned and is now sailing due south at 48 km/hr. What is the magnitude of his average acceleration over this period of time?
A 25 kg mass starts from rest and is forced to the right with a force of 14.98 Newtons and has a force of friction of 7.49 Newtons. Determine the distance the mass travels in 19.98 seconds.
Vector lengths of 30m, 500m and X create a resultant length of 10m. What could X be?
A 15.98 kg sky diver falls and experiences an upward force due to air resistance of 10.99 N at a point in time. Determine the magnitude of the acceleration the sky diver experiences at this time.
Use the following situation to answer questions 10 & 11. A 10.99 kg wagon is pulled to the right with a 15.98 N force that is applied at an angle of 30 degrees with respect to the horizontal. There is a 4.99 Newton force of friction pulling the wagon to the left.
Determine the acceleration of the wagon.
Determine the final velocity of the wagon after a time of .3996 seconds if it starts from rest.
For questions 12 - 14 below use the following situation: Two forces act concurrently on a 25 kg mass: a 69.95 Newton force at 45 degrees along with a 98.92 Newton force at 120 degrees.
Determine the magnitude of the net force provided by these two forces.
Determine the force that would need to act along with these two forces to put a zero net force on the 25 kg mass.
Determine the direction at which the force in Question 13 would need to act in order to put a zero net force on the 25 kg mass. (use 0 degrees east as reference)
