NOTE: Do the easier one, only need to complete 1 of the 2!

1)

A box of mass 90.1 kg that is initially at rest is pulled by a rope at an angle of 30.0 from the horizontal along a floor with a kinetic coefficient of friction of 0.696. A force of 767 N acts on the rope.

Draw a free-body diagram of the situation. In your free-body diagram, include all of the involved forces resolved into the horizontal and vertical directions. Use your free-body diagram to determine how long it will take for the box to be moved 20.7 m horizontally.

2)

A student tosses a snowball from the top of their school's roof to the ground below at a velocity of 35 m/s angled 43 above the horizontal. The snowball leaves the student's hand at a height of 16.2 m.

Draw a free-body diagram of this situation that shows all forces acting on the snowball (ignore wind resistance).

How long will the snowball be in the air before it hits the ground and at what horizontal distance from the school will the snowball land?
