We can use the formula:
force = mass x acceleration
Plugging in the given values, we get:
force = 0.145 kg x 80 m/s^2
force = 11.6 N
Therefore, the pitcher applied a force of 11.6 N to the baseball.

A negative acceleration occurs when an object is slowing down. In other words, its velocity is decreasing over time. Here are some situations that describe negative acceleration:
1. A car is driving forward and suddenly brakes, causing its speed to decrease rapidly. The car is experiencing a negative acceleration.
2. A ball is thrown straight up in the air, but starts to slow down as it reaches the top of its trajectory before falling back down. At this moment, the ball is experiencing a negative acceleration.
3. A roller coaster is at the top of a loop and starts to slow down as it starts to descend. The roller coaster is experiencing a negative acceleration at this moment.
