a.
To find: At what instance projectile will be back at ground level.
a.
Answer to Problem 74E
After
Explanation of Solution
Given information:
A projectile is fired upward from ground level
Concept used:
The position equation for a projectile is given as-
Calculation:
A projectile is fired upward from ground level
So,
Using position equation, when projectile hit back at the ground
Therefore, projectile will hit the ground after
b.
