A roller coaster car is traveling 1 m/s at the top of the track. At the bottom of the track, 5 seconds later, it is traveling 36 m/s. What is its average acceleration? Show your work. Delta Symbol= ∆
(a)
Which of the following is the best explanation for why the crumpled ball of paper will hit the ground first?
The crumpled paper will fall faster because there
is less air resistance from the surface slowing its
motion.
The crumpled paper will fall faster because there
is less gravity acting on it from the surface slowing its
motion.
If two balls that look exactly the same but have different masses are dropped at the same time from the top of the ladder, what would be the best explanation for what we will observe?"
The balls should not fall at the same rate even if they
have different masses because the acceleration of
gravity is different for each object.
The balls should fall at the same rate even if they
have different masses because the acceleration of
gravity is constant.
Student 1, you can't have a negative acceleration. It
means that the car’s speed is decreasing.
Student 2, the s2 comes from km per s (speed) divided
by time (s). km/s/s = km/s2

Two students made a video recording of a basketball as it was dropped. They recorded the time and position of the basketball at each frame. They made this data table based on the first eight frames of the recording. In 8 frames, the basketball traveled 20.4 cm. Use the data table to answer the questions. Choose True if the statement is true; choose False if the statement is false. _____ The acceleration the students calculated for the ball for each time interval is not constant.
True
False
