Question

На какую высоту поднимается стрела если выстрелил и из арбалета со скоростью 60м/с

Answer 1

(m/2)*(v^2) = mgh,
(v^2)/2 = gh,
h = (v^2)/(2g).
h = (60*60)/(2*10) м = 360/2 м = 180 м.

Answer 2

Calculating the Height of the Arrow Shot from a Crossbow

To calculate the height to which the arrow rises when shot from a crossbow with a velocity of 60 m/s, we can use the following formula:

h = v0^2 / (2g)

Where: - h = maximum height reached by the arrow - v0 = initial velocity of the arrow (60 m/s in this case) - g = acceleration due to gravity (approximately 9.81 m/s^2)

Calculation

Using the given initial velocity (v0 = 60 m/s) and the acceleration due to gravity (g = 9.81 m/s^2), we can calculate the maximum height (h) reached by the arrow.

h = v0^2 / (2g) h = 60^2 / (2 * 9.81) h ≈ 183.74 meters

Therefore, the arrow reaches a maximum height of approximately 183.74 meters when shot from the crossbow at a velocity of 60 m/s.
