Want this question answered?
4ft*Ns=H
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
it means initial upwards height times time in seconds
the answer is 24-9 m/sec. yuor welcome
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
4ft*Ns=H
"8 seconds" is not a velocity.
That depends on its initial velocity and its acceleration. V1 = V0 + a * t
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
A ball thrown vertically upward returns to the starting point in 8 seconds.-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by(9.8 meters/second2) x (4 seconds) = 39.2 meters per second-- So that had to be the magnitude of its initial upward velocity.

it means initial upwards height times time in seconds
51 seconds.
After just over three and a quarter seconds.
.866 seconds
the answer is 24-9 m/sec. yuor welcome
