- Jill is flying a kite that weighs
8 N where the string is at a 40° angle to the
horizontal. She applies a force of 75 N to the
string in order for the kite to remain in place.
- Draw a force diagram of the kite
- Write the net force equations for the horizontal
and vertical dimensions
- Determine the value for all forces
- Explain what would happen if all of a sudden the
wind completely died

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
