Answer:
Due to its function to fight against disease.
Explanation:
Improvement of strength in the human body is very important because strong body helps in fighting against diseases. Strong body helps in doing physical activities and also helps in protecting itself from every type of harm. Weak human body can't fight against diseases due to weak immune system so we can conclude that improvement in human body is necessary for survival, development and health of human.
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s
