Answer 1

Через координату x надо было найти

Answer 2

Calculation of the Final Velocity of the Ball

To calculate the final velocity of the ball at the end of the chute, we can use the following equation of motion:

v^2 = u^2 + 2as

Where: - v is the final velocity of the ball - u is the initial velocity of the ball (which is 0 in this case) - a is the acceleration of the ball (given as 1.6 m/s^2) - s is the distance traveled by the ball (given as 125 cm or 1.25 m)

Plugging in the values into the equation, we get:

v^2 = 0^2 + 2 * 1.6 * 1.25

Simplifying the equation, we have:

v^2 = 2 * 1.6 * 1.25

v^2 = 4

Taking the square root of both sides, we find:

v = 2 m/s

Therefore, the final velocity of the ball at the end of the chute is 2 m/s.
