Want this question answered?
An archer uses a force of 60.0N to draw back the string of his bow through a distance of 0.330m. He then fires a 300g arroe straight up into the air. What is the maximum speed of the arrow at the instane it leaves the bow? What is the maximum height reached by the arrow in its flight into the air?
51 seconds.
yes because they have the same gravitational potential
40.81632653 or (rounded to the nearest 10th) 40.8 seconds
By an arrow, a vector. Velocity is a vector quantity that must have both magnitude (speed) and direction (bearing).

This is a velocity question so u need to use uvaxt

Velocity.
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Straight as an Arrow was created on 2008-11-30.
If the arrow was fired in a direction making an angle x with the horizontal, and assuming that acceleration due to gravity is 32 feet per second^2 ijn the downward direction, then its height at time t iss(t) = 160*sin(x)*t - 16*t^2.
The change in velocity is 51-100 = -49 m/s This occurred over a period of 5 seconds so The (negative) acceleration - aka - deceleration is (-49 m/s)/(5 s) = -9.8 m/s²
v = a*t + vinitial; d = 1/2*a*t + vinitial * t plug in to second equation to find v initial: 35 = 1/2 (-9.8)*(3) + vinitial * (3) vinitial = 26.37m/second From here, you can solve for average velocity by finding starting velocity and ending velocity (use the first equation): vave = (vfinal + vinitial) / 2 vave = (-3.03 + 26.37) / 2 = 11.67m/s Note: the arrow will reach maximum height at 2.69 seconds, so the 3.03 is negative (the arrow is coming down at 3 seconds).
so the arrow will spin and fly straight. P.S. it makes it fly farther.
as straight as a ruler?as straight as an arrow
