Question

Snookie is riding in her little red wagon (total mass of 215 kg) at a constant speed of 9.5 m/s. All of a sudden a magenta lemur (19.7 kg) appears in her lap. How fast is the Snook-meister traveling now?

Please show work.

Answer 1

8.7 m/s

Step-by-step explanation:

Momentum before = momentum after

m₁ u = (m₁ + m₂) v

(215) (9.5) = (215 + 19.7) v

v = 8.7 m/s
