Question #1062

A heavy mass on a frictionless ramp at an angle of 30 degrees drags a 2 kg mass upward using a pulley. if the tension in the rope is 30 N, what is the acceleration of the 2 kg mass?

Expert's answer

Let's write II Newton's law for the mass:

ma = T - mg sin(α);

a = T/m - g sin(α) = 30/2 - 10 sin(30) = 10 m/s^{2}

ma = T - mg sin(α);

a = T/m - g sin(α) = 30/2 - 10 sin(30) = 10 m/s
