Question

4. СКОРОСТЬ ПАРАШЮТИСТА ПРИ ВЫБРАСЫВАНИИ ПАРНЮТА УМЕНЬШАЕТСЯ НА 40 м/е ЗА 4 с. НАЙДИТЕ УСКОРЕНИЕ, С КОТОРЫМ «ТОРМОЗИТ» ПАРАШЮТИСТ.

Answer 1

Ответ: a=10м/с^2

Объяснение:

V=Vo-at

Подставим значения:

0=40-4а => а=10м/с^2

Answer 2

Speed reduction of a parachutist during parachute deployment

When a parachutist deploys their parachute, their speed is reduced. The question asks for the acceleration with which the parachutist "brakes" or slows down. To find this acceleration, we can use the given information that the parachutist's speed decreases by 40 m/s in 4 seconds.

To calculate acceleration, we can use the formula:

acceleration = (change in velocity) / (time)

In this case, the change in velocity is -40 m/s (negative because the speed is decreasing) and the time is 4 seconds. Plugging these values into the formula, we get:

acceleration = (-40 m/s) / (4 s) = -10 m/s^2

Therefore, the acceleration with which the parachutist "brakes" or slows down is -10 m/s^2.
