Question

An arrow is shot from a height of 1.20 m toward a cliff of height H. It is shot with a velocity of 32.8 m/s at an angle of 60 degrees above the horizontal. It lands on the top edge of the cliff 3.90 s later.

a. What is the height of the cliff

b. What is the maximum height reached by the arrow along its trajectory

c. What is the arrows impact speed just before hitting the cliff

Expert Solution

Step 1: Given data

Initial height of object is $h subscript i equals 1.20 space straight m$

Final height or height of cliff is $H$

Initial velocity is $u equals 32.8 space straight m divided by straight s$

Angle of projection is $theta equals 60 to the power of degree$

Time taken by object to reach the top of cliff is $t equals 3.90 space straight s$

Find:

(a) The height of cliff.

(b) The maximum height reached by object during the motion.
