Answer:
x sin nx = x cos nx
same as
theta / theta x (xsin (nx)) = sin (nx) + (nx) cos (nx)
I believe its the third answer
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

Answer:
D
Explanation:
F=ma
F of 5 kg rock = 49N
F of 10 kg rock = 98 N
Divide by respective masses to get acceleration, and of course you will get 9.8 m/s^2 for both.
Now, use potential energy equals kinetic energy. mgh=(1/2)mv^2 mass cancels out of the equation, since it's on both sides, so we can stop right there. We have algebraically determined that mass does not affect acceleration or velocity!
Hope this helped.
