F = (mass)(acceleration) = ma
m = 0.2 kg
Vi = 32 m/s
t = 0.5 s
Vf = 0 m/s (since it was put to stop)
a=(Vf-Vi)/t
a=(0-32)/0.5
a = 64 m/s^2 (decelerating)
F = ma = (0.2 kg)(64 m/s^2)
F = 12.8 N

a) 1000 grams = 1 kg ... no
d) 1000 centigrams
The image height is -10 cm (the image is upside down)
Explanation:
We can solve the problem by using the mirror equation:

where:
f = 5 cm is the focal length of the mirror
p = 10 cm is the distance of the object from the mirror
q is the distance of the image from the mirror
Solving for q, we find:

So, the distance of the image from the mirror is 10 cm.
Now we can find the image height by using the magnification equation:

where
y' is the height of the image
y = 1 cm is the height of the object
and using
p = 10 cm
q = 10 cm
We find the size of the image:

where the negative sign indicates that the image is upside down.

Answer:
Force = 19.62 Newton
Explanation:
Given the following data;
Mass = 2kg
Acceleration = 9.81 m/s²
To find the force;
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Substituting into the formula, we have;
Force = 2 * 9.81
Force = 19.62 Newton
