Correct Question:
Compare the kinematics equation governing the motion and the format of the fit equation that you just made
to explain how you can use the coefficients (either A, B, or C) to calculate the acceleration due to gravity. 13 pts Identify the coefficients of your fit equation. 5 pts
A =
В =
C =
Answer:
A = g/2
B = v₀
C = 0
g = 2A
Explanation:
.............................(1)
............................(2)
Comparing equations (1) and (2)
A = g/2
B = v₀
C = 0
Acceleration due to gravity can be gotten from A = g/2 above
g = 2 A.....................(3)
Therefore, if we know the coefficient A, we can get the acceleration due to gravity using the relation in equation (3)
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of
Initial velocity of (opposite direction)
Final velocity of (same direction )
Final velocity of (same direction)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Answer:
Explanation:
Mechanical Energy=Potential Energy+ kinetic Energy
To calculate Kinetic Energy:-
To calculate Potential Energy:-
therefore,
The skydiver's total mechanical energy is 459365J
