B. the object's speed and mass

Looking at the kinetic energy formula:

1/2mv^2 = Ek

It can be seen that the only two factors that affect the magnitude of the kinetic energy are mass and the object speed. Kinetic energy is also a scalar quantity so the direction is unnecessary.

Fittoniya [83]
For distance vs time graphs, the slope stands for speed, as speed is a scalar, along with distance.
For displacement (position) vs time graphs, the slope stands for velocity, as velocity is a vector, along with displacement.

Earth characteristics compared to other planets (kids explanation)
jasenka [17]

While Earth is only the <u>fifth largest planet in the solar system</u>, it is <u>the only world </u>in <u>our solar system</u> with the life we know or are starting to know of, for example, us as human beings. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. Other planets such as Jupiter are not so likely to have life like us there, for it is full of gas we don't breathe, and gases which are harmful to us, unlike the oxygen we have here on earth.

A raft of mass 199 kg carries two swimmers of mass 52 kg and 70 kg. The raft is initially floating at rest. The two swimmers sim
Minchanka [31]

To solve this problem we will apply the concept related to the conservation of the Momentum. We will then start considering that the amount of initial momentum must be equal to the amount of final momentum. Considering that all the objects at the initial moment have the same initial velocity (Zero, since they start from rest) the final moment will be equivalent to the multiplication of the mass of each object by the velocity of each object, so

Initial Momentum = Final Momentum

(m_B+m_1+m_2)v_i = m_1v_1+m_2v_2+m_Bv_B

Here,

m_B =  mass of Raft

m_1 = Mass of swimmers 1

m_2 = Mass of swimmers 2

v_i = Initial velocity (of the three objects)

v_B = Velocity of Raft

Replacing,

(199+52+70)*0 = (52)(4)+(70)(-4)+199v_B

Solving for v_B

vB = \frac{72}{199}

v_B = 0.3618m/s

Therefore the velocity the rarft start to move is 0.3618m/s
