The answer is the acceleration increases
Answer
given,
length of the track = 200 m
speed of runner 1 = 6.20 m/s
speed of the runner 2 = 5.5 m/s
distance covered by the fastest runner, d = 6.2 t
distance covered by the slow runner,d = 5.50 t + 200
time taken to overtake for the first time
6.2 t = 5.50 t + 200
0.7 t = 200
t = 285.7 s
distance covered from the starting point
d = 6.2 t
d = 6.2 x 285.7
d = 1771.43 m
for next overtaking time taken will be double
t' = 258.7 x 2 = 571.4 s
distance travel by the runner from the starting point
d' = 6.2 t'
d' = 6.2 x 571.4
d' = 3542.68 m
Answer: check explanation.
Explanation:
The acceleration of the system means the acceleration of the centre of mass of the system. So, let's take a quick look at the first two laws of Newton.
Newton's first law states that any object at rest that is not acted upon by outside forces will remain at rest, and that any object in motion not acted upon by outside forces will continue its motion in a straight line at a constant velocity. This laws seems to be at odd with our everyday lives. Let's take a look at the his second law.
Mathematically, the second law can be represented as; F=Ma. The law states that object will accelerate in the direction of the net force.
In order to know the acceleration of attached objects attached to a pulley we need to consider the system of objects as one object, followed by measuring the effect of the net external forces with respect to the ratio of the total mass of the system.
A red apple absorbs all colors of visible light except red, so red light
is the only light left to bounce off of the apple toward our eyes.
(This is a big part of the reason that we call it a "red" apple.)
Here's how the various items on the list make out when they hit the apple:

The answer is C the earth axis is tilted
