You shoot an arrow into the air at an initial velocity of 12.5m/s at an angle of 40º.
- Find the maximum height the arrow reaches in the air.
- Find the time it takes to reach its maximum height.
- Find the time it takes to hit the ground. Assume its flight in the air is symmetrical, with the first half of flight traveling upward, and the 2nd half of flight traveling downward.
- Find how far away it hits the ground.
Solutions
Expert Solution
Given:
Initial launch velocity of the arrow, 
Launch angle, 
-------------
Find the maximum height the arrow reaches in the air.
Use formula 
ANSWER: 
============================
Find the time it takes to reach its maximum height.
Consider the vertical motion of the arrow
Use formula 
At maximum height, vertical velocity becomes zero
Initially, the arrow is going up and g is acting downwards. So put a negative sign for g.
ANSWER: 
=========================
Find the time it takes to hit the ground.
Use the formula 
to find the time of flight
ANSWER: 
===========================
Find how far away it hits the ground.
Use the formula 
to find the range of the arrow.
