Use the first kinematic formula
Vf = Vi + at
10 = 0 + 1(t)
10 = t

Because sometimes it happens that they discover a dwarf planet
that nobody ever knew about before. When that happens, they
ADD the new one to the list of known dwarf planets, and then the
total number of dwarf planets on the list increases by 1 .
Do the data support or refute the hypothesis, normally, the data for the first part of the experiment support the first hypothesis.
<h3>What is a hypothesis test?</h3>
Hypothesis testing refers to the formal procedures used by statisticians to accept or reject these hypotheses. When trying to make decisions, it is convenient to formulate assumptions or conjectures about the populations of interest, which consist of considerations about their parameters.
As a result of this, we can see that from the complete text, there is a set of data which is used to show the force that is applied to a cart that causes the acceleration of the cart to increase which supports Newton's second law.

Answer:
The magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
Explanation:
The Universal law of gravity is define as:
(1)
Where F is the gravitational force, G is gravitational constant, M is the mass of Mars, m is the mass of the lander and R is the radius of Mars.
Before replacing the values in equation 1 it is necessary to express the radius of mars in terms of meters:
R = ⇒ R =
Finally, equation 1 can be used:
Hence, the magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
