good day all i've no idea how to work this out this is the problem A 5.5-kg object is suspended by a string from the ceiling of an elevator that is accelerating downward at a rate of 2.5m/s^2 What is the tension in the string? i presume tension is the force thats on the string? so i did: 5.5(kg) * (9.8(grav) - 2.5) = 40.15N is this correct? the equation i was given is: Fnet = T + Fg which i rearranged to get T = Fnet - Fg what the hell does that mean? lol could someone tell me a general rule for tension?
