Answer:
you can simply answer by derivative = 3.5x^2+25x+250-y=0 you can derivate this eqn 7x +25-1=0 7x=24 yo u can divide you get it
Answer:
a.
b.
Explanation:
Given:
Mass of the baseball =
The initial velocity of the baseball = 20m/s
The force acting on the baseball is only due to gravity and the air resistance is negligible. The baseball acceleration is constant due to gravity.
According to Newton's second law:
----------(1)
where mass of the baseball
Put all the value in equation 1.
Therefore, the force on the ball when it reaches half of its maximum height is .
Similarly, the force acting on the ball when its peak .
Answer:
2m/s²
Explanation:
- V=Vstart+at
- rewrite that to find a so a=(V-Vstart)/t
part A of graph
part B of graph
the average between the two is both answers added divided by the number of answers
- (4m/s²–0m/s²)/2
- 4m/s²/2
- 2m/s²
