Answer: 0.16
Explanation:
Newton's second law states that the resultant of the forces exerted on the bookcase is equal to the product between the mass (m) and the acceleration (a):
where
F = 58 N is the force applied
Ff is the frictional force
Substituting, we find the frictional force
The frictional force has the form:
where is the coefficient of kinetic friction. Re-arranging the formula, we can find the coefficient:
Answer:
The location is at (3.535, 1.162) m
Solution:
As per the question:
Mass of the projectile, m = 9.6 kg
Initial velocity, v = 12.4 m/s
Angle,
Mass of one fragment, m = 6.5 kg
Time taken by the fragment, t = 1.42 s
Height of the fragment, y = 5.9 m
Horizontal distance, x = 13.6 m
Now,
To determine the location of the second fragment:
Horizontal Range,
Time of flight, t' =
Now, for the fragments:
Mass of the other fragment, m' = M - m = 9.6 - 6.5 = 3.1 kg
Distance traveled horizontally:
Distance traveled vertically:
Now,
x' = 3.535 m
Similarly,
The location of the other fragment is at (3.535, 1.162)
