Assume that the scoop shown, which is 20 cm wide, is used as
a braking device for studying
deceleration effects, such as those on
space vehicles. If the scoop is attached
to a 1000-kg sled that is initially
traveling horizontally at the rate of 100
m/s, what will be the initial deceleration
of the sled? The scoop dips into the
water 8 cm (d = 8 cm). (T = 10°C.)
