A ball of clay is thrown at a wall at a velocity of 28.0 m/s. After it hits the wall, it takes 0.020 s to stop. What is the acceleration of the clay when it hits the wall?

• 1400 m/s²

• -1400 m/s₂

• 0.56 m/s²

• -0.56 m/s²

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval
