Question

С поверхности земли вертикально вверх бросили мяч со скоростью 4 м/с

Answer 1

S=(V^2-Vo^2)/(2*g)

S=(16-1)/(2*10)=15/20=0.75 м

Answer 2

Initial Conditions

If a ball is thrown vertically upward from the surface of the earth with a speed of 4 m/s, we can calculate various parameters related to its motion.

Calculating Initial Velocity and Height

The initial velocity (v0) of the ball is given as 4 m/s The height (h) can be calculated using the formula: h = (v0^2) / (2g), where g is the acceleration due to gravity, approximately 9.81 m/s^2.

Calculating the Height

Substituting the given values: h = (4^2) / (2*9.81) h ≈ 0.816 meters.

So, when the ball is thrown vertically upward from the surface of the earth with a speed of 4 m/s, it reaches a height of approximately 0.816 meters.
