Freely Falling Bodies with Linear Trajectories
On this worksheet you will practice working with
freely falling bodies
released vertically as a special example of uniformly accelerated motion.
A ball is thrown straight down off a 15-meter balcony at a speed of 7 m/sec. How many seconds will it take to hit the ground at the base of the balcony?
will the ball in
be traveling just as it impacts the ground?
If the ball in
had instead been thrown straight upwards at a speed of 7 m/sec off the 15-meter balcony, how much time would it have taken to strike the ground at the base of the balcony?
True or False. The ball in
will strike the ground moving at a faster speed than the ball released in
above the release point
did the ball in
rise during its trajectory?
From the instant when the ball was tossed upwards in
, how much time was required before the ball once again passes through its release position?
A walnut drops from the top branch of a walnut tree and falls a total distance of 20 meters. After one second, it clears all of the tree's foliage. How much additional time passes before it strikes the ground at the base of the tree?
What was the walnut's final velocity just as it impacted with the ground?
