Question

A ball initially at rest rolls down a hill with an acceleration of 3.3 m/s². After it accelerates, the ball rolls across a flat surface at a constant velocity. What is this constant velocity?

Answer 1

The constant velocity at which the ball rolls across the flat surface after accelerating down the hill can be calculated using the equation: Constant velocity = Initial velocity + (acceleration)(time). The specific constant velocity can be determined by substituting the time value into the equation.

Step-by-step explanation:

The constant velocity at which the ball rolls across the flat surface after accelerating down the hill can be found by using the equation:

Constant velocity = Initial velocity + (acceleration)(time)

Since the ball starts at rest (with an initial velocity of 0 m/s) and accelerates down the hill with an acceleration of 3.3 m/s², the constant velocity can be calculated as:

Constant velocity = 0 + (3.3 m/s²)(time)

Therefore, the constant velocity of the ball depends on the amount of time it takes to accelerate down the hill. If you have the specific time value, you can substitute it into the equation to find the constant velocity.
