Question
At time t = 0, an object is launched from ground level, with an initial speed of 80 m/s and at a launch angle i
At time t = 0, an object is launched from ground level,
with an initial speed of 80 m/s and at a launch angle i
such that cos i = 2/3 and sin i = 3/4.
The object then travels in a symmetric, parabolic path.
What is the object's height above the ground 1 second before it reaches the top of its path?
