If you're riding your bike at constant velocity, then the magnitude of the force of thrust -a- the magnitude of force of friction, but the two forces are in -b- directions.

a) is less than, is greater than, is equal to
b) opposite, the same, perpendicular

What would the answer be and why?

Inertia is NOT a force, right?

So, it would be best described as... (CHOOSE ALL THAT APPLY)

mass
resistance to change in velocity
the tendency to maintain constant velocity
the force of gravity
resistance to acceleration
a force within the object
a property of matter

A piece of cheese is at rest. A gerbil pulls to the left with 1.5 N at the same time as a mouse pulls to the right with 1.5 N.
a) what is the net force on the piece of cheese? 0 N

b) What does the cheese do in this situation? choose ALL that apply:
moves with constant non-zero velocity
accelerates at a constant rate
remains at rest
maintains constant velocity
speeds up
moves with a changing velocity
slows down

A high tech jet car speeds along the desert floor at a constant velocity of 180 miles/hr north. what is the net force on the jet car?

The jet car hits some sand which causes a drag force on the car of 5000 N to the south. The computer instantly compensates so the jet exerts a thrust force on the car of exactly 5000 N to the north at the same time the car hits the sand. The jet car now... choose ALL that apply:
slows down
remains at rest
maintains constant velocity
moves with constant non-zero velocity
speeds up
moves with a changing velocity
accelerates at a constant rate

What happens?

A uniform rod of length L1= 1.8m and M=2.4kg is supported by a hinge at the right end and is free to rotate in the counter-clockwise direction. The rod is released from a horizontal position and hits a particle of mass m (which is supported by a thin string of length L2=1.4m from the hinge. The particle sticks to the rod on contact. After the collision, theta max =35degrees

a) Find mass of particle, m

b) How much energy is dissipated during the collision

If you could give me an explanation, that would be great. Perhaps some laws or principles that I could follow for an upcoming exam? I don't quite understand the relationship between Watts and Calories in the mathematical/theoretical sense.
