4 kg mass swings in circle of radius 80 cm and the end of mass less rope what resonant or is required to give an angular acceleration of 2 red second raise to the power square
To calculate the tension in the rope required to give an angular acceleration of 2 rad/s^2, we can use the equation:
Tension = (mass * radius * angular acceleration) / radius
Given:
mass = 4 kg
radius = 80 cm = 0.8 m
angular acceleration = 2 rad/s^2
Tension = (4 kg * 0.8 m * 2 rad/s^2) / 0.8 m
Tension = 8 N
Therefore, a tension of 8 N is required to give an angular acceleration of 2 rad/s^2.
