A rocket-powered hockey puck has a thrust of 2.20 and a total mass of 0.700 . It is released from rest on a frictionless table, 2.90 from the edge of a 2.80 drop. The front of the rocket is pointed directly toward the edge.
2.2 what? dynes?
0.700 what? carats?
2.9 what? chains?
2.8 what? rods?
Ya gotta include the units.
It also helps to state just what it is you want to know. You have presented some rather unclear data, and we are left wondering, So, what?
