Question

с вертолета летящего горизонтально на высоте 320м со скоростью 50м/с сброшен груз. а) сколько времени будит падать груз( сопротивлением воздуха принебреч)? б)какое расстояние пролетит груз по горизонтале за время падения? в) с какой скоростю груз упадет на землю

Answer 1

Calculation of Time of Fall

To calculate the time it takes for the object to fall, we can use the formula:

time = height / velocity

Given that the height is 320m and the velocity is 50m/s, we can substitute these values into the formula:

time = 320m / 50m/s

Calculating this, we find that the time it takes for the object to fall is approximately 6.4 seconds.

Calculation of Horizontal Distance Traveled

To calculate the horizontal distance traveled by the object during the fall, we can use the formula:

distance = velocity * time

Given that the velocity is 50m/s and the time is 6.4 seconds, we can substitute these values into the formula:

distance = 50m/s * 6.4s

Calculating this, we find that the horizontal distance traveled by the object is approximately 320 meters.

Calculation of Final Velocity

To calculate the final velocity of the object when it hits the ground, we can use the formula:

final velocity = initial velocity + (acceleration * time)

Since the object is falling vertically, the initial velocity is 0m/s and the acceleration due to gravity is approximately 9.8m/s^2. The time is 6.4 seconds. Substituting these values into the formula, we get:

final velocity = 0m/s + (9.8m/s^2 * 6.4s)

Calculating this, we find that the final velocity of the object when it hits the ground is approximately 62.72m/s.

Please note that these calculations assume no air resistance.
