Question

WILL MARK BRAINLIEST ONLY IF YOU SHOW WORK

Answer 1

Answer:

Following are the solution to the given points:

Explanation:

In point a:

$v_i = 4.56 \ \frac{m}{s}$

In point b:

The highest point : v=0

In point c:

$a= -g \ \frac{m}{s^2} = -9.8 \frac{m}{s^2}$

In point d:  

The highest point: $a= -9.8 \ \frac{m}{s}$  

In point e:

$v^2=v_i^{2}+2g \Delta h \ \ \ \ \ \ Delta h=0\\\\v^2 = v_i^{2}\\\\v= 4.56 \ \ \frac{m}{s}$

Therefore, the velocity of the ball when it reaches into the hand $4.56 \ \frac{m}{s}$.
