The spring will come to rest 4.9 m below the natural length
Explanation:
The mass-spring system will come to rest when the restoring force on the spring (pulling upward) balances the weight of the mass (pulling downward). Mathematically, this can be written as
where
k is the spring constant
x is the elongation of the spring
m is the mass
g is the acceleration of gravity
In this problem, we have:
is the mass
is the acceleration of gravity
is the spring constant
Solving the equation for x,
Therefore, the spring will come to rest 4.9 m below the natural length.

To calculate the acceleration of the truck, we use the equation of motion
Here, v is final velocity of the truck, u is initial velocity of truck, a is acceleration of the truck and t is time taken.
Given, u = 6 m/s, v = 14 m/s and t = 4 s.
Substituting these values in above equation, we get
.
Thus, the truck acceleration is 
Answer:
"The weight of an empty bottle is 10N...Calculate the mass of the empty bottle."
w=Weight; m=Mass; g=Gravity
w=mg
w/g=m
10/9.81=m
1.019368kg = m
Explanation:
Her cells will not work well when they have low levels of oxygen.
Answer:
so the acceleration of the body would be zero because there is no change in velocity
