A catapult launches a rocket at an angle of 49.6° above the
horizontal with an initial speed of 112 m/s. The rocket engine
immediately starts a burn, and for 3.58 s the rocket moves along
its initial line of motion with an acceleration of 32.5
m/s2. Then its engine fails, and the rocket proceeds to
move in free-fall.

A ladder 25 feet long is leaning against the wall of a house.
The base of the ladder is pulled away from the wall at a rate of 2
feet per second.
How fast is the top of the ladder moving down the wall when the
base is 15 feet from the wall?

A catapult launches a test rocket vertically upward from a well,
giving the rocket an initial speed of 79.4 m/s at ground level. The
engines then fire, and the rocket accelerates upward at 3.90 m/s2
until it reaches an altitude of 1200 m. At that point its engines
fail, and the rocket goes into free fall, with an acceleration of
−9.80 m/s2. (You will need to consider the motion while the engine
is operating and the free-fall motion separately.) (a)...

A catapult launches a test rocket vertically upward from a well,
giving the rocket an initial speed of 79.2 m/s at ground level. The
engines then fire, and the rocket accelerates upward at 3.90
m/s2 until it reaches an altitude of 1060 m. At that
point its engines fail, and the rocket goes into free fall, with an
acceleration of −9.80 m/s2. (You will need to consider

A catapult launches a test rocket vertically upward from a well,
giving the rocket an initial speed of 80.8 m/s at ground level. The
engines then fire, and the rocket accelerates upward at 4.20 m/s2
until it reaches an altitude of 990 m. At that point its engines
fail, and the rocket goes into free fall, with an acceleration of
❝9.80 m/s2. (You will need to consider the motion while the engine

A hi-tech high-powered catapult is located at point A and is
aimed at an angle of = 45 ° with the horizontal.
The projectile launched from the catapult is just able to clear
the peak of the mountain at the top of its
trajectory. The elevation of the catapult is 423 m above sea
level and the distance d is 4031 m.
Find the following:
(a) The velocity V0 that the projectile leaves the
catapult (in m/s),
(b) The time...
