Answer the following questions. a
1) Fill in the blank.
Based on the video, record on the chart the distances (nearest hundredth) the ball traveled from the
ramp's top after different times. This will give you the velocities in Round to the nearest hundredth
HINT: You will need to convert the velocities in In/s to m/s.
1 inch = 2.54 cm
100 cm = 1 m

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
