Answer:
22 is the jsksnenekeond snLL
Answer:
Step-by-step explanation:
We are in the case of vertical shot. If we neglect air resistance, the only force acting over the ball is gravity. As gravity acts down to earth and the ball is going up, speed´s ball will be decreasing by gravity ( 9.8 m/sec²) That means the speed of the ball will be decreasing 9.8 m/sec, each second.
When the ball get the maximum height Vy = 0 then the ball stars descending, and when the ball is descending again gravity is the only force acting gravity acts in the same direction as the ball´s movement, so the ball´s speed will increase at a rate of 9.8 m/sec each second.
It is a well known fact that the time of the ball to get maximum height is the same as for the ball to fall down to earth. In other words time from the beginning of the movement up to maximum height is equal to time for the ball to fall down.
Answer:
A
Step-by-step explanation:
The line is divided into 9 parts between 1 and 2
A is situated 6 parts of the way between 1 and 2, that is
= 
← cancelling by 3
Hence
A = 1 + = 1 → A
