Desperate for a help with tension in rope!! Two blocks are connected by a cable via a pulley which are massless and frictionless. Given the following: m1 = 300.0 kg, m2 = 100.0 kg, theta=40degrees, uk=.350 ,what is the tension in the cable? So have figured out the acceleration to be .304m/s the acceleration is going down the plane, but I don't know which equation to use for T: T-m2g=m2a OR m1gsin40+T-Fk=m1a I think it is the 1st one, but that doesn't take into account the friction? Anyhelp? This is due in 2 hours!!! Thanks!
