<u>Final Velocity = 8.06 m/s</u>
<u>Option : B</u>
<u>Explanation:</u>
Let be the mass of player,
be the mass of the ball,
be the initial speed of the player,
be the initial speed of the ball and
v be the final speed of the player after the catching the ball.
Applying conservation of momentum, we can solve for the final speed of the player after the catching the ball when the ball and player move in the same direction.
<u>Here:</u>
= 110 Kg
= 0.410 Kg
= 8.0 m/s
= 25.0 m/s
=
=
V = 8.06 m/s
Answer:
B. The algebraic sum of the two electric potentials is determined at a distance r/2 from each of the charges, making sure to include the signs of the charges.
Explanation:
Total electric potential is the sum of all the electric potential. And because electric potential is a scalar quantity you have to account for the signs.
Answer:
I'd say 2) "Genes are instructions that cells use to create proteins." Because it's more specific, and that's essentially what it's for.

b
Explanation:
From the question we are told that
The maximum height is H = 2.70
The Range is R = 12.9 m
Generally from projectile motion we have that
Generally from trigonometric identity
So
=>
Also the maximum height is
=>
=>
=>
=>
Dividing equation 2 by (1)
=>
=>
=>
So
From equation 1
=>
Generally the vertical component of the initial velocity is mathematically evaluated as
=>
=>
Generally the time taken is mathematically represented as
=>
=>
