Because of prevailing winds, a tree grew so that it was leaning in such a way that it formed a 94° angle with level ground. At a point 35 meters from the tree, the angle of elevation to the top of the tree is 23º. (NOTE: The tree is leaning away from the point from which the angle of elevation is being measured.) Find the height of the tree. *Do not include units in your answer, round to the nearest...

Problem 7 4. A projectile of mass 9.6 kg is launched from the ground with an initial velocity of 12.4 m/s at angle of 54° above the horizontal (see the figure). At some time after its launch, an explosion splits the projectile into two pieces. One piece, of mass 6.5 kg, is observed at 1.42 seconds after the launch to be at a height of 5.9 m and at a horizontal distance of 13.6 m from the launch point Find...

While examining the terrain, from the top of an
extraterrestrial tree H 100 [m] high a heavy fruit is detached, at
that moment you were on the ground directly below (see figure), and
reacting quickly manages to draw his weapon in such a way that
simultaneously shoots a super projectile with initial speed of 50 m
/ s upwards with the intention of destroying the fruit.
Determine:
a) The height at which the projectile impacts the
fruit.
b) The speed...
