Answer:
a)this graph is also a line b) in both cases we have a uniform movement
Explanation:
In this exercise we have a uniform movement
v = d / t
d = v t
in the table we give some values to make the graph
t (s) d (m)
1 10
2 20
3 30
In the attached we can see the graph that is a straight line
we have another vehicle at v = 50 me / S
t (s) d (m)
1 50
2 100
3 150
this graph is also a line
b) in both cases we have a uniform movement
Answer:
B. 8,437.5 J
Explanation:
<u>Given the following data;</u>
Height = 400m
Mass = 75kg
Velocity = 15m/s
Time = 10 secs
To find the kinetic energy of the skier?
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
<em>Where;</em>
- <em>K.E represents kinetic energy measured in Joules. </em>
- <em>M represents mass measured in kilograms. </em>
- <em>V represents velocity measured in metres per seconds square. </em>
<em>Substituting into the equation, we have;</em>
K.E = 8,437.5 Joules.
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another inside a gravitational field, the force of gravity will do positive work on the object and the gravitational potential.

FORMULA:
ANSWER:
We are given with mass of car 394kg and velocity of car 15m/s.
Plugging the respective value,
- K.E. = 1/2 × 394 × 15²
- K.E. = 197 × 225
- K.E. = 44,325J
