    1. The problem statement, all variables and giv
    A construction worker is pulling a bucket filled with wet cement using a smooth pulley. The total mass of the bucket is 5kg.

    2. Relevant equations

    F=ma

    3. The attempt at a solution
    F=5*2ms^2
    = 10 N

    The answer is 60N

    Right so you have the tension acting in one direction and the weight of the mass in the other. The resultant of those two is 10 N. So what is the tension in the rope? (this is the force they are asking for).
