A 0.023 kg golf ball moving at 18.9 m/s crashes through the window of a house in 5.4 × 10−4 s. After the crash, the ball contin-

ues in the same direction with a speed of 10.1 m/s.
Assuming the force exerted on the ball by the window was constant, what was the mag- nitude of this force?
Answer in units of N.

Force can be expressed as the time-rate change of momentum

Mathematically, Force = Change in momentum/change in time

Change in momentum = m(10.1-18.9) = -0.2024

Force = -2024/5.4 = -375N(approx)

The significance of the '-' sign is that the direction of force is the opposite that of the direction of our velocities since we assumed them to be positive.

Also this is the force on the ball, the force on the window will be equal and opposite.

What is the purpose of the article physicists test telepathy in a cheat proof setting?
ryzh [129]
I'm guessing that the purpose of the article is to inform the
general public of the work that these Physicists did when they
attempted to detect the existence or non-existence of telepathy
in a controlled, scientifically acceptable setting.

The REASON the article was ever presented in a non-professional
publication was most likely in deference to the general public's interest
in telepathy, UFOs, aliens, flat Earth, Astrology, and all other forms of
weird garbage.  In other words, its publication was motivated more by
the desire to sell magazines than by any inclination to impart any real,
useful information to the general public.
