Answer:
Group and Periods of the Periodic Table of Elements. The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
So, first the formula of Impulse is
I = force * time
We have force but no time.
Then, find time.
Next find acceleration,
F = mass * acceleration
5 = 3 * a
1.67 m/s^2
Next find time,
Acceleration = change in velocity / time
Change in velocity is velocity final - velocity initial
1.67 = 3 - 9 / time
Time = 3.6 s (round to 2 s.f.)
Lastly,
Impulse = force * time
Impulse = 5 * 3.6
Impulse is 18 Ns
Answer: Normal Force of the ground pushing the athlete up.

Answer:
100 watt
Watt is a unit of power, for the light bulb its produces or consumes 100 watts of power
If we have a vector P, then we name it's components by the axis we project it onto.
In 2D Cartesian coordinate system we have one x axis and one y axis.
Vector P can then be represented with two components: Px and Py.
Px is the component of vector P on the x axis and Py is the component of the vector P on the y axis.
