Answer:
acceleration= velocity ÷ time
Explanation:
the question is outrageous
Answer: SOLUTION
Explanation: A technological design is often adopted when there is a need to solve or find solution to a certain or identified problem. The technological design process is often required in other to develop technologically driven products which is capable of providing solution to a perceived problem. The steps involved includes;
Identifying the problem at hand, carrying out further and thorough research on them, proferring possible solutions out of which the best possible approach is selected. Then the solution is modeled, the model is tested and refinements are made depending on outcome of the test. Testing will have to be repeated upon refinement of the model before the final outcut is communicated.
Star 1 - 4 hours right ascension
Star 2 - 3 hours right ascension
Subtracting hours right ascension
4 hours right ascension - 3 hours right ascension = 1 hours right ascension.
Thus,
1) star 1 will rise 1 hour before star 2
You can find
1) time to hit the ground
2) initial velocity
3) speed when it hits the ground
Equations
Vx = Vxo
x = Vx * t
Vy = Vyo + gt
Vyo = 0
Vy = gt
y = yo - Vyo - gt^2 / 2
=> yo - y = gt^2 / 2
1) time to hit the ground
=> 8.0 = g t^2 / 2 => t^2 = 8.0m * 2 / 9.81 m/s^2 = 1.631 s^2
=> t = √1.631 s^2 = 1.28 s
2) initial velocity
Vxo = x / t = 6.5m / 1.28s = 5.08 m/s
3) speed when it hits the ground
Vy = g*t = 9.81 m/s * 1.28s = 12.56 m/s
V^2 = Vy^2 + Vx^2 = (12.56 m/s)^2 + (5.08 m/s)^2 = 183.56 m^2 / s^2
=> V = √ (183.56 m^2 / s^2) = 13.55 m/s
