1) Horizontal velocity, Vx
Vx is constant and equal to 5.0 m/s
The graph Vx(t) = 5.0 m/s is a horizontal line (parallel to the horizontal t-axis). that intercepts the vertical-axis at 5.0 and runs from t = 0 to t = 2.
2) Vertical velocity, Vy
Vy = gt = 10t
d = at^2 / 2 => tmax = √(2d / a) = √(2*20m/10m/s^2) = 2 s
Graph Vy is an inclined line with slope 10 m/s^2, that runs from t =0 to t = 2 s, and passes through the points (0,0), (1,10), and (2,20).
Dredging is what the inventor of this machine need to know while developing the machine.
Hope this helps!
The height of the light house is 17.86m.
To find the answer, we have to know about the simple pendulum.
<h3>How to find the height of the light house?</h3>
- We have the expression for time period of the pendulum as,
where, g is acceleration due to gravity, and l is the length of the pendulum.
- For the pendulum with time period T kept at some height under the influence of gravity, then the height will be equal to,
Thus, we can conclude that, the height of the light house is 17.86m.

Answer:
Total Mechanical Energy of the gymnast = 1940J = 1.94 kJ
Explanation:
Total Mechanical Energy = KE + PE + SE
Kinetic Energy,
Potential Energy,
Strain Energy,
Since there is no force of deformation, x = 0, SE = 0
Total Mechanical Energy = 225 + 1715
Total Mechanical Energy of the gymnast = 1940J = 1.94 kJ
Answer:50 miles per hour 50/1hr
Explanation:100 divided by 2 is 50, divide 2 by 2 thats 1
