Question

Пушка и цель находятся на одном уровне на расстоянии 5,1 км друг от друга. Через сколько времени снаряд, вылетевший с начальной скоростью 240 м/с, достигнет цели?

Answer 1

5,1км=5100 м
t=S/V=5100/240=21,25 сек

Answer 2

Calculation of Time Taken by the Projectile to Reach the Target

To calculate the time taken by the projectile to reach the target, we can use the formula:

time = distance / velocity

In this case, the distance between the cannon and the target is 5.1 km (or 5100 meters), and the initial velocity of the projectile is 240 m/s.

Plugging these values into the formula, we get:

time = 5100 / 240

Calculating this, we find that the time taken by the projectile to reach the target is approximately 21.25 seconds.

Therefore, the projectile will take approximately 21.25 seconds to reach the target.
