Answer:
The required acceleration is
m/s²
Explanation:
Given
To determine
Acceleration a = ?
We know that acceleration is produced when a force is applied to a body.
The acceleration can be determined using the formula

where
now substituting F = 250 , and m = 221 in the formula


switch the equation

Divide both sides by 221

simplify

m/s²
Therefore, the required acceleration is
m/s²

in my opinion I'd say it's gravity because it's making the book stay in it's one and only position pulling the book at the center of the desk
Answer:
144 ft
Explanation:
h(t) = -16t² + 64t + 80
The maximum height is at the vertex. We can find the vertex of a parabola using -b / (2a):
t = -64 / (2×-16)
t = 2
The vertex is at 2 seconds. The height of the stone at this time is:
h(2) = -16(2)² + 64(2) + 80
h(2) = 144
The maximum height is 144 feet.
Answer:
I think it is 2.5 kg.
Explanation:
I can say you do:
Fnet = m * a
So, you want to find mass:
m = Fnet / a
So, the answer you will receive is 2.5
