Type one to two paragraphs that describe the potential energy, kinetic energy, and the thermal energy of the cart.
a) Type one to two paragraphs describing the changes in potential, kinetic, and thermal energy
of the cart at each of the four positions along the track. Be sure to define your system. Also
include the positions of the cart where each form of energy is at its maximum and minimum
values.

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
