answer: v=3m/s
Answer:
Mars.
Explanation:
It only has a little over 24 hours in a day, its rotation axis is tilted about the same as earths, and I MAY actually have some water on its surface.(Though none has been discovered YET)
Hope this helps lots and lots,
sincerely, me
We use the formula
to find the initial velocity
We have:
Initial velocity (u) = 12 m/s
Acceleration (a) = 14 m/s²
Distance (s) = 48 meters
We are looking to find the final velocity (v)
Substituting these values into the formula, we have:
v² = 12² + 2(14)(48)
v² = 144 + 1344
v² = 1488
v = √1488
v = 38.57 m/s
Answer:
Explanation:
Check attachment for solution
Since both hv same mass and elsstic collision, so their velocity will exchange. Bob A will stop and bob B will move with speed of A just before the collision.
Speed will be = squreroot ( 2*g*L)
L is length of pendulum
