Question

Refer to your lab guide and review the data in Table B to complete each statement.

The mass of G1 + G2 after the collision is
kg.

The velocity of G1 + G2 after the collision is
m/s.

The momentum of the combined gliders after the collision is
kg · m/s

Answer 1

I don’t have your lab guide or Table B, so I can’t fill in the numeric answers yet. I can show how to get each value — paste the numbers from Table B (masses and velocities) and I’ll compute them for you.

Formulas and steps
- Mass of G1 + G2 after collision:
mass_total = m1 + m2 (kg)

- If momentum is conserved and they stick together, the velocity after collision is
v_after = (m1·v1_initial + m2·v2_initial) / (m1 + m2) (m/s)
(Or use the measured combined velocity from Table B if given.)

- Momentum of the combined gliders after the collision:
p_after = (m1 + m2)·v_after = m1·v1_initial + m2·v2_initial (kg·m/s)

Example
- If m1 = 0.100 kg, m2 = 0.150 kg, v1_initial = 0.60 m/s, v2_initial = 0.00 m/s:
mass_total = 0.100 + 0.150 = 0.250 kg
v_after = (0.100·0.60 + 0.150·0.00) / 0.250 = 0.06 / 0.25 = 0.24 m/s
p_after = 0.250·0.24 = 0.060 kg·m/s (also equals 0.100·0.60 = 0.060)

Send the masses and velocities from Table B (and whether velocities are in m/s or need unit conversion), and I’ll compute the three values with correct units and sig figs.
