Answer:
17.6kg.m/s in the opposite direction of the initial velocity.
Explanation:
In order to solve this we can use the Impulse-Momentum theorem:

We will assume the motion of the ball approaching the player as positive, so:

So the impulse is 17.6kg.m/s in the opposite direction of the initial velocity.
Answer:
You are right. It is reflected
Explanation:
if it is concave then the light is reflected at one direction.
if it is convex the light is reflected outwards and they will travel away from the focal point and the light scatters or will be reflected to different directions
B. The temperature of the water.
The independent variable is the variable that is changed to affect the dependent variable. In this instance, the temperature of the water is being changed to affect the amount of sugar that dissolves.

Explanation:
a. Action: Earth pulls on the Moon, reaction: Moon pulls on Earth;
b. Action: foot applies force to ball, reaction: ball applies force to foot;
c. Action: rocket pushes on gas, reaction: gas pushes back on rocket;
d. Action: car tires push backward on road, reaction: road pushes forward on tires;
e. Action: jumper pushes down on ground, reaction: ground pushes up on jumper;
f. Action: gun pushes forward on bullet, reaction: bullet pushes backward on gun
Usually the unit of measurement of velocity is meters per second or m/s
