Answer:
Explanation:
When force applied to the end of the rod in perpendicular direction then net torque on the rod is given as
Now another force is applied at mid point of the rod at an angle of 30 degree with the rod
so new value of torque is given as
so we have
Power is the ratio between energy and time:
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
