Coach mitchell was playing catch with his son (who is 1/2 meter tall) in the yard one day and told him to throw the ball so
that it reached a maximum height of 10 meters. after 4 seconds the ball was again level with his son's hand, but he
missed it and the ball hit the ground.
1. give an equation, h(t), in vertex form that models this situation and graph it (height vs. time). explain what each
characteristic of the parabola means in the context of this problem.
2. the ball then rolled along the ground for several seconds. write a function, f(t) that models the height of the
ball over the interval 0

answer: d. $20

step-by-step explanation:

just took the test

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
