A 2.50 kg object placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 7.50 kg object, as in Figure P5.24. Find the magnitude of the acceleration of the two objects and the tension in the string.
acceleration of 2.50 kg object
acceleration of 7.50 kg object
tension in string
well i figured out the second part that the acceleration is 7.35. i used the formula a=F/m. F= 9.8 X 7.5. however i tried to doing the same for the first 1 and it said the answer was wrong. i did a=F/m. F=2.5x9.8=24.5/2.5=9.8 which was wrong. also for the tension i can't figure it out until i find the a for first part. then i plan to use the formula...T=2m1m2/m+m2*9.8...would that be the right forumla?
