While in empty space, an astronaut throws a ball at a velocity of 15 m/s. What will the velocity of the ball be after it has traveled 2 meters?

It is 10 on Study Island.

To find the velocity of the ball after it has traveled a certain distance, we need to consider the concept of acceleration. In this case, assuming there are no external forces acting on the ball, we can use the constant acceleration formula.

The formula to calculate velocity when acceleration is constant is:
v² = u² + 2as

Where:
v = final velocity
u = initial velocity
a = acceleration
s = distance traveled

Since the astronaut throws the ball in empty space, there is no air resistance or any other force acting on the ball once it is released. Therefore, we can assume the acceleration is zero.

Plugging in the given values:
u = 15 m/s (initial velocity)
a = 0 m/s² (acceleration)
s = 2 meters (distance traveled)

The formula becomes:
v² = 15² + 2 * 0 * 2

Simplifying further:
v² = 225

Taking the square root of both sides to solve for velocity:
v = ±15

The positive value is the velocity in the direction the ball was thrown. Therefore, the velocity of the ball after traveling 2 meters will be 15 m/s.

u aint cool u don't know anything u GOT IT WRONG!!!!!!!!!!!!

It's 15

it would be 11 because an object in motion will stay in motion unless stop by another object and it wont get stopped in space

it 12 , i check it and got it correct

13

It's 15
