The sweeping second hand on your wall clock is 24cm long.
a)what is the rotational speed of the second hand? b)find the translational speed of the tip of the second hand.
c)find the rotational acceleration of the second hand.

1) a child holds two dogs on two separate leads. the dogs are pulling in different directions. one is pulling a force of 20n north and one is pulling 15n eastwards. calculate the resultant force on the child. state the direction. (use the parallelogram of forces) 2) a force of 20n acts horizontally on an object. a second force of 5n acts at 60 degrees to the first one. calculate the resultant force. worth 20 points, need answers asap with method you x
