A 1.5 m long frictionless pendulum of mass 1.6 kg is released from point A at an angle 0 of 10 degrees. What is the speed of the pendulum at point D, half the height up to point E? A) 0.18 m/s

B) 0.36 m/s

C) 0.47 m/s

D) 0.67 m/s

i think they are all correct

explanation:

they seem good

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

well clustered together.
