A big man and small boy push away from each other on ice. Who moves away faster?
The man
They are the same
They don't move they have equal and opposite force.
The boy

Puck has v
i
20 m/s. Slides 115 m before stopping. What is ǔ
k
?
0.089
0.182
0.177
0.165
4
A particle in equilibrium must
have acceleration
be moving
not be moving
may be moving but at constant velocity
5
What are the units for Force?
Newtons
Watts
Joules
Kiligrams
6
Determine the acceleration of each mass. See pic.
ay= (m2 - m1)/(m1 + m2)
ay= (m2 + m1)/(m2-m1)
ay=(m1-m2)/(m2-m1)
ay= (m1-m2)/(m1+m2)
7
Same as previous question. Who moves farther?
The boy
The man
They both move the same
The ice
8
Which is usually greater static friction or kinetic friction?
They are the same
Static
Neither
Kinetic

length of the ramp
mass of the object
10
What is an inertial frame of reference?
A frame where non- Newtonian Phyiscs hold true.
Where you can take a snap shot of an object
A frame where Newtonian mechanics hold.
A frame where mass is constant,
