A stone is dropped at t = 0. A second stone, with twice
the mass of the first, is dropped from the same point at t
= 234 ms.
How far below the release point is the center of mass of the two
stones at t = 326 ms? (Neither stone has yet
reached the ground.)

that time?
1) A stone with mass 240 g is swirled around using a 0.2 m long
rope such that it makes 10 full revolutions in 17 seconds. a) The
speed of the stone is v = m/s. b) The tension in the rope is T = N.
c) Work done by the tension force is W = J.
2) A puck is kicked up an icy incline with an initial speed of

A mixture of NaCl and NaBr has a mass of 2.00 g and is found to
contain 0.78 g of Na.

Express your answer using two significant figures.
Two air track gliders of mass 400.0 g and 300.0 g are moving
towards each other in opposite directions with speeds of 60.0 cm/s
and 100.0 cm/s, respectively. Take the direction of the more
massive glider as positive. Use units of "g" and "cm/s" in your
calculations.
Determine the velocity of each glider after the collision if
the collision is elastic. (Use units of "g" and "cm/s" for this
question.)
The most "inelastic" collision would occur if the two gliders...
a cart of mass of 420 g moving on a frictioless horizontal
linear air track at an initial speed of 1.4 m/s undergoes an
elastic collision with an initially stationary cart of unknown mass
M. after the collision the initial cart moves with a speed pf 0.76
m/s. (a). what is the mass of the cart . b) what is the velocity of
the second cart after the collision .
A cart with mass 330 g moving on a frictionless linear
air track at an initial speed of 2.1 m/s undergoes an
elastic collision with an initially stationary cart of unknown
mass. After the collision, the first cart continues in its original
direction at 1.05 m/s. 1.) What is the mass of the second
cart? 2.)What is its (second cart) speed after impact? 3.)What is
the speed of the two-cart center of mass?
A geologist finds that a Moon rock whose mass is 9.08 kgkg has
an apparent mass of 6.06 kgkg when submerged in water.

appropriate units.
Two pucks collide on an air hockey table. Puck A has a mass of
17.0 g and is initially traveling in the +x direction at 7.30 m/s.
Puck B has a mass of 51.0 g and is initially at rest. After the
pucks collide, puck A moves away at an angle of 42.0 degrees above
the +x axis, while puck B travels at an angle of 38.0 degrees below
the +x axis.
1. Calculate puck A's final speed.
2. Calculate...
