Answer:
640 N
Explanation:
Given :
Mass of horse, m = 40kg
initial speed of horse, u = 8 m/s
final speed of horse, v = 0 m/s (because horse comes to a sudden stop)
time taken to stop, t = 0.5 s
recall that acceleration = change in speed / time taken for the change
or
a = (v - u) / t (substituting the above values)
a = (0 - 8) / 0.5
a = -16 m/s² (i.e it is a deceleration of 16 m/s²)
since we are not concerned about the direction of the force, we can simply use the absolute value of acceleration which is a = 16 m/s²
also recall that
Force = mass x acceleration
F = ma (substituting the values above)
F = 40kg x 16 m/s
F = 640 N

_____
However, it will take an additional 0.514 seconds (0.714 s total) for the policeman to land on the building below. The answer depends on the meaning of the question.
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
