Answer:
Higher mass or higher speed
Explanation:
Higher mass will require more force
F= ma if m goes up F goes up to stop in the same distance
Answer:
If jack is in the piece of furniture it would submerge.
Explanation:
The piece of furniture would submerge if the weight applied on the furniture is greater than the maximum buoancy force the water can provide.
maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.
= 
v = area × thickness of pine

= 0.075 
therefore buoancy force = 1025×0.075×9.8 N
= 753.375 N
weight of rose alone = 46×9.8 N = 450.8 N
weight of jack alone = 58×9.8 = 568.4 N
weight of pine = density of pine × volume of pine
= 350 × 0.075= 26.25 N
weight of pine + weight of rose = 450.8+26.25=477.05 N
weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N
therefore if jack is in the piece of furniture it would submerge.

Since the greatest number in the given electron configuration of the atom is 4, it means that the element is found in the fourth energy level. The number of electrons found in the valence shell is 2+10+6 = 18. From this answer and using the periodic table, we can see that the atom is that of Krypton (Kr).
Given data
*The given mass of the rock is m = 2 kg
*The given potential energy is U_p = 407 J
(a)
The diagram of the energy bar graph is drawn below
(b)
If an object is at rest and has potential energy, once it starts to fall from its rest state then this potential energy is completely transferred to kinetic energy. This means that the magnitude of the kinetic energy is equal to the potential energy of the object.
The change in kinetic energy of the rock while falling to the ground is given as

(c)
The formula for the speed of the block is given as
![\begin{gathered} U_k=\frac{1}{2}mv^2 \\ v=\sqrt[]{\frac{2U_k}{m}} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20U_k%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%5C%5C%20v%3D%5Csqrt%5B%5D%7B%5Cfrac%7B2U_k%7D%7Bm%7D%7D%20%5Cend%7Bgathered%7D)
Substitute the known values in the above expression as
![\begin{gathered} v=\sqrt[]{\frac{2\times407}{2}} \\ =20.17\text{ m/s} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20v%3D%5Csqrt%5B%5D%7B%5Cfrac%7B2%5Ctimes407%7D%7B2%7D%7D%20%5C%5C%20%3D20.17%5Ctext%7B%20m%2Fs%7D%20%5Cend%7Bgathered%7D)
Hence, the speed of the object is v = 20.17 m/s
