A 4.0 kg projectile is launched into the air with an initial
velocity of 15 m/s at an angle of 30° above the horizontal. When
the projectile reaches its maximum height it explodes, splitting in
two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the
explosion was essentially instantaneous.
Determine the maximum height of the projectile using energy.
After the explosion, if the 1.0 kg mass is moving at 1/2 the
speed it was right...

Romeo is standing 30 m (horizontally) from Juliet’s balcony, and
he throws her a bouquet of
flowers, tossing them with a speed of 20 m/s at an angle of
53.1° above horizontal. Juliet catches
the flowers, inhales their fragran
ce, and swoons.
(The air, as ever, is unwilling to interfere with
young love, so it offers no resistance to the
motion of the flowers.)
(a) Somewhere along their trajectory between
Romeo and Juliet, the flowers will reach their
maximum height....

In order to get full credit, you need to show all your
work.
A ball is launched from the top of a 60 m high building with an
initial speed v0 at an angle 40° above the
horizontal (close to the surface of Earth). Air resistance is
negligible during the motion of the ball.
On the coordinate system shown with origin on the ground, draw
the path of the ball, the initial velocity vector, and its vector
components. Then find...
