Question
An experimental rocket sled weighs 5200 lb and is propelled by six rocket motors each with an impulse rating of 8600 lb-sec. The rockets are fired at 1-sec intervals, and the duration of each rocket firing is 2 sec. If the velocity of the sled 10 sec from the start is 200 mi/hr, determine the time average R of the total aerodynamic and mechanical resistance to motion. Neglect the loss of mass due to exhausted fuel compared with the mass of the sled.
*I got confused because there are three different times here: 1)interval, 2)burn time, and 3)time to travel distance.
Thank You

time to travel distance is actually asked.if yiu still fell any difficulty then asked for further assistance
