Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.
Answer:earth, water, air, fire, and (later) aether, which were proposed to explain the nature and complexity of all matter in terms of simpler substances.

The answer is attached below
The net force is -5 N so the box will move backwards
Answer:
<h2>
<u>76.36m/s</u></h2>
Explanation:
Step one:
given data
let the mass of the rider be m,=110kg
let the velocity be v=?
let the mass of the car be M,=110kg
let velocity of the car V=6m/s
Step two:
the momentum of an object is given by the expression
P=mv
<em />
Step two:
<em>since the two the bicycle rider must have the same momentum as the car,</em>
<em>then we need to equate their momentum</em>
mv=MV
110*v=1400*6
110v=8400
divide both sides by 110 to find v
v=8400/110
v=76.36m/s
<u>The rider is expected to have a speed of 76.36m/s</u>
