An arrow is shot straight up in the air with an initial speed of
240 ft/s. If on striking the ground it embeds itself 8.00 in into
the ground, find the magnitude of the acceleration (assumed
constant) required to stop the arrow, in units of
feet/second^2.
In the shot put, a heavy lead weight—the "shot"—is given an
initial velocity, starting from an initial elevation approximately
equal to the shot putter's height, say, 2.00 m. If v0 = 7.05 m/s,
find the horizontal distance traveled by the shot for the following
initial angles above the horizontal.
theta 0 =?
theta 40.0 = ?
theta 45.0 = ?
In the shot put, a heavy lead weight—the "shot"—is given an
initial velocity, starting from an initial elevation approximately
equal to the shot putter's height, say, 2.00 m. If
v0 = 7.90 m/s, find the horizontal distance
traveled by the shot for the following initial angles above the
horizontal. (a) θ0 = 0°
(b) θ0 = 40.0°
(c) θ0 = 45.0°
From the castle wall 20m high shot an arrow. The initial speed
of the bow is 45 m/s directed 40 degrees above the horizontal.
Find the initial velocity components.
Find the maximum height of the arrow.
Find the range.
Find an arrow final velocity.
A ball is kicked in a large level field. The ball’s initial
horizontal velocity is 20.00 m/s. The ball’s initial vertical
velocity is 15.00 m/s.

A projectile is shot straight up from the earth's surface at a
speed of 5000km/hr .
How high does it go?
Express your answer with the appropriate units.
a baseball player hits a ball straight up with an initial
velocity of 109 miles. Reaches a height of s = 0.03t-0.003t^2 miles
after t seconds. What is the speed of the ball when it is at 0.0827
miles off the ground?
You throw a ball straight up with an initial velocity of 17.0
m/s. It passes a tree branch on the way up at a height of 9.50 m.
How much additional time will pass before the ball passes the tree
branch on the way back down?
Give your answer in seconds.
A shot putter threw a shot at an angle of 43o above the
horizontal from a height of 2.0 m above the ground. The shot
traveled 19.0 m horizontally from the launch position. (a) What was
the initial speed of the shot when it left the shot putter’s hand?
(b) How long was the shot in the air? {13.0 m/s, 2.0 s}
A golfer hits a ball from the horizontal ground, giving it an
initial velocity of 35 m/s at an angle of 28º to the horizontal.
Where will the ball be 2.4 s after it is hit?
What will be the greatest height reached by the ball?
Where will the ball land?
A rock is thrown at 45º from an initial height of 1.8 m from
the ground. The rock reaches its maximum height 2.0 s after its
release.
