The answer is B preserve the front wheel alignment.
kinematics allows to find the kinetic variables and the relationships between position, speed and acceleration, for launching projectiles we can find:
a) The horizontal velocity vₓ = 2.1 m/s
b) The height of the table y₀= 0.60 m
given parameters
- Time to reach the floor t = 0.35 s
- Horizontal distance x = 0.75 m
to find
a. Horizontal speed
b. table height
Let's use the kinematics relations, let's start by defining a reference frame with the x-axis along the motion of the ball and the vertical y-axis with the positive direction up.
We look for the initial velocity in the x axis, there is no acceleration we can use the uniform kinematic relations
vₓ = x / t
Where vx is the horizontal velocity, g the acceleration of gravity (g=9.8 m/s²) and t the time
vₓ = 0.75 / 0.35
vₓ = 2.14 m / s
We look for the height of the table that corresponds to the initial height (y₀) of the ball, when reaching the floor the height is zero, on the vertical axis the initial velocity is zero (v_{oy} = 0)
y = y₀ + v_{oy} t - ½ g t²
0 = y₀ + 0 - ½ g t²
y₀ = ½ g t²
y₀ = ½ 9.8 0.35²
y₀i = 0.60 m
- In conclusion with the kinematic relations for the launch of projectiles we can find the horizontal velocity vₓ = 2.1 m / s and the height of the table i = 0.60 m

Answer:
When you play basketball, you play on a surface called a Court with 2 symmetrical halves, both consisting of a basket or net on each end. The aim of the game is to score the most points or baskets in the allotted time. Rules vary from league to league but in the NBA games last for 48 minutes with four quarters of 12 minutes. In a basic basketball game, the time limit can be changed or it can be a game of the first to a certain number of baskets.
Teams
You can play in teams which can consist of 1 to 5 players however you can also play on your own as well when practising or executing Drills. Playing with friends can be useful to help share advise and have more opportunities to learn and easily begin to understand basic basketball rules through playing regularly.
Positions
Each player has his or her own position name on the court and this is usually determined by height, speed and agility. The tallest players are usually allocated Centre position, and they are usually available to rebound both defensively and offensively as well as being the best player for tip off. These players in the NBA can range from 6ft,7 to 7ft+ The next tallest players are usually Forwards and the fastest of these are called Power forwards. The smallest players are called Guards who are usually the quickest, both physically and mentally and who co-ordinate all the plays laid down by the coach of the team.
Basic Rules
When moving the basketball around the court, the players must travel around using a technique called Dribbling. To dribble the player must not take more than a step and a half without the ball coming into contact with the court and back to the players’ hand again in a bouncing motion. If more than 1 and a half steps are taken this is a Travelling violation. Once the player has stopped dribbling they may not move again until the ball comes to them from another player. Each shot taken can be done either inside or outside the shooting Area. Outside the shooting area a successful shot is worth 3 points and inside the area is worth 2 points. However inside the shooting area, there is an area named The key in which players may not remain for More than 3 seconds to prevent goal hanging. Additional single points can be scored from the free throw line in a penalty.
These are all basic basketball rules and there are many others that need to be obeyed in order not to violate the rulebook but as a beginner are not necessary to learn until you have mastered the basics.
