The discussion revolves around calculating the average thrust force of a toy rocket with a mass of 90g that reaches a velocity of 80m/s in 3.0 seconds. Participants are exploring the dynamics involved in this scenario, particularly focusing on the effects of gravity and the application of Newton's laws.
The discussion is active, with participants providing various approaches and questioning assumptions. Some guidance has been offered regarding the use of free-body diagrams and the relationship between thrust and weight, but there is no explicit consensus on the correct method or solution yet.
Participants mention the need to consider the effects of gravity and whether the mass of the rocket changes during the flight, indicating potential constraints in the problem setup. There is a sense of urgency as one participant notes a deadline for completing the work.
Sucks@Physics said:avg acceleration = 26.667m/s and lol yea its on earth
aq1q said:ok, start out by drawing a free-body diagram. since the thrust is accelerating upwards.. thrust must me greater than weight. therefore Ft-W=Ma soo Ft=w+ma, right?
Solve for a, and then just plug and chug..
