Answer:
Magnitude the net torque about its axis of rotation is 1.3338 Nm
Explanation:
The radius of the wrapped rope around the drum, r = 1.24 m
Force applied to the right side of the drum, F = 4.56 N
The radius of the rope wrapped around the core, r' = 0.57 m
Force on the cylinder in the downward direction, F' = 7.58 N
Now, the magnitude of the net torque is given by:
where
= Torque due to Force, F
= Torque due to Force, F'
Now,
The net torque comes out to be negative, this shows that rotation of cylinder is in the clockwise direction from its stationary position.
Now, the magnitude of the net torque:
Answer:
Part a)
Part b)
Part C)
This is loss in terms of thermal energy due to collision with the floor
Explanation:
Part a)
Since we know that the ball rises up by 65% of initial height
so after first bounce it will lose 35% of its initial energy
so we will have
Energy Loss = 0.35 mgH[/tex]
Part b)
Energy of the ball after first bounce
energy of ball after 2nd Bounce
energy of the ball after 3rd bounce
Now we will have energy loss in fourth bounce given as
Part C)
This is loss in terms of thermal energy due to collision with the floor
