Answer: x = 0.957 m
Explanation:
F = ma
d = ½at²
a = 2d/t²
F = m2d/t²
F = kx
kx = m2d/t²
x = 2md/kt²
x = 2(8.86)(4.36) / (471(0.414²))
x = 0.957036...
Answer:
(a) The density of the object is 316/343 × the density of the oil
(b) The fraction of oil displaced after immersing the object is 0.461 of the oil volume
Explanation:
(a) The volume, V of a cone of height, h and base diameter, D = 2×r is given by the following equation;

The volume of the object is therefore;

Where 6 cm is above the oil level we have;
above the oil level
Therefore, volume of the oil displaced =
cm³ = 216.11 cm³
The density of the object is thus;

The density of the object = 316/343 × the density of the oil.
(b) The volume of the oil = 2 × Volume of the object = 
The fraction of the volume displaced, x, after immersing the object is given as follows;

The fraction of oil displaced after immersing the object = 0.461 of the volume of the oil
Answer:
a=4m/s2
Explanation:
Vi= 20m/s
S=150 m
t= 5 sec
a=?
using 2nd equation of motion;
S= Vit+0.5at^{2}
putting values
150= (20)(5)+0.5(a)(
)
150-100= 12.5a
50/12.5 =a
4m/s2=a
Answer:
u are falling
Explanation:
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
