Question

Тело брошено вертикально вверх со скоростью 30 метров на секунду Вычислите его скорость через 1 секунду после начало движения (сопротивление воздуха не учитывается)

Answer 1

V0=30, t=1сек, g направлена вниз, тогда v=v0+gt, v=30-10*1=30-10=20м/с. Вроде так)

Answer 2

Calculation of the Velocity of an Object Thrown Vertically Upwards

To calculate the velocity of an object thrown vertically upwards, we can use the equation:

v = u + gt

Where: - v is the final velocity - u is the initial velocity - g is the acceleration due to gravity (approximately 9.8 m/s^2) - t is the time elapsed

In this case, the object is thrown vertically upwards with an initial velocity of 30 m/s. We need to calculate the velocity after 1 second.

Using the equation, we can substitute the given values:

v = 30 + (-9.8)(1)

Simplifying the equation:

v = 30 - 9.8

v = 20.2 m/s

Therefore, the velocity of the object after 1 second is 20.2 m/s
