Find the average of those numbers, add all the divide by 5
That statement is only true sometimes. If you use 500 and 10, 10% of 500 is 50, while 20% of 10 is only 2. Clearly, 50 is larger than 2.
the vertical component of the casting velocity will be reduce to zero at point h by the force of gravity.
If we use the kinematic equation
vf² = vi² +2as
and realize that the final vertical velocity is zero
and the initial vertical velocity is vsinθ
where θ is the angle of cast above the horizon
0 = vsin25 + 2(-9.8)h
h = 0.423v / 19.6
h = 0.02156v
so the missing potential heights and the associated answer velocities are
v = 19 m/s...h = 0.410 m
v = 8.3 m/s...h = 0.179 m
v = 6.9 m/s...h = 0.149 m
v = 8.4 m/s...h = 0.181 m
choose the one that fits the question
or use the method to find the correct velocity based on the actual height reference frame.
