Answer:
(a). The time is 26.67 sec.
(b). The distance traveled during this period is 1066.9 m.
Explanation:
Given that,
Speed = 80 m/s
Acceleration = 3 m/s
Initial velocity = 0
(a). We need to calculate the time
Using equation of motion
Put the value into the formula
The time is 26.67 sec.
(b). We need to calculate the distance traveled during this period
Using equation of motion
The distance traveled during this period is 1066.9 m.
Hence, This is the required solution.
Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.
Mango takes 1.009 seconds to reach the ground.
<h3>What is free fall ?</h3>- A situation in which an object moves solely under the influence of gravity is referred to as free fall. An external force acts on the ball, causing it to move faster. This free fall acceleration is also known as gravitational acceleration. The term "free fall" refers to a downward movement with no initial force or velocity.

h =
where,
h = height = 5m ,
t = time ,
g =gravity = 9.8 m/s.
= 2h / g = 10/9.8 = 1.02
t= = 1.009 sec
