The total acceleration in the x-direction for an object in projectile motion.
Zero.
This type of friction is a variable force. It can have magnitude of any number up to a certain calculated limit.
Static Friction
The work done on a system is equal to its change in kinetic energy of that system.
The work-energy theorem
An explosion is the reverse of this type of collision.
Perfectly inelastic collision

The direction of the speed of a boat trying to travel directly north across a river that has a current traveling east.
North-West
The velocity defined by the maximum speed achieved by a falling object under the influence of a drag force.
Terminal Velocity
For an oscillating object, this kind of energy is greatest at the equilibrium point.
Kinetic Energy
The resultant angular direction of the center of mass for a system of two equal masses that collide where one is initially traveling directly North and the other is initially traveling directly East.
45 degrees north of east or east of north

The acceleration of a car moving with speed v = 2t + 3t2 at time t = 4 seconds.
a = 26
The tension in the rope in the following picture if the mass of the hanging object is 200kg.
980 N
The derivative of the energy with respect to time.
Power
The law that governs the values of internal forces between objects in a collision.

Assuming air resistance is negligible, this is true of the object's acceleration at the highest point the object reaches for an object thrown through the air which follows a parabolic path.
It is constant or it is equal to the acceleration due to gravity. 9.8 is not a valid answer (I never said the object was thrown on earth).
The force on block 2 in terms of F in the following diagram if block 2 has mass twice that of block 1's mass.
2/3 F
The ratio of the work done by person 1 and person 2 if they have the same mass and person 1 travels up a flight of stairs at a constant velocity and person 2 travels up the same flight of stairs at a constant velocity double that of person 1.
1:1, they do the same amount of work.
The location of the center of mass for an uniform density equilateral triangle with height length L if the center of the base of the triangle is located at the origin.
(0, L/3) or L/3 above the origin.

The maximum distance an object fired from ground to ground can travel on Earth if it has initial velocity of 5 m/s assuming g=10m/s2.
x = 2.5m
The magnitude of the uniform acceleration of the train car shown given that there is a 37 degree angle made with respect to the vertical for the hanging mass.

The potential energy of a spring when it has been compressed a distance x0 if the relationship between the magnitude of the restoring force F and the resultant displacement x from equilibrium for the nonlinear spring is given by the equation F = kx2.
E = 1/3 kx03
The velocity of an object of mass M at t=2 seconds if it is at rest at t=0 and a force F=At2, where A is a constant, is applied.
v = 8A/3M
