1. Fill in the missing gaps in the sentences. Then match them up
with the pictures of a skydiver who has just jumped out of ar
aeroplane.

. it is
As she accelerates faster, the resistance force
now the
as her weight. She now moves at a
speed because the
force acting on her is zero. She is now at her
velocity(She cannot go any faster)
As she decelerates the air resistance force on her parachute
until it is the
size as her weight.
She is now moving with a
speed until she hits the
ground - a new, slower
velocity
2. Now draw arrows to represent the different forces acting on the
skydiver and label them with the types of force. Make the length
of your arrow show the size of the force i. e a long arrow represent
a large force.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
