1. Understand the Concepts
* Impulse: Impulse is the change in momentum of an object. It's equal to the force applied multiplied by the time over which the force acts.
* Momentum: Momentum is the product of an object's mass and velocity.
2. Calculate the Change in Momentum
* Initial Momentum: (mass) * (initial velocity) = (0.15 kg) * (35 m/s) = 5.25 kg*m/s
* Final Momentum: (mass) * (final velocity) = (0.15 kg) * (0 m/s) = 0 kg*m/s
* Change in Momentum: Final momentum - Initial momentum = 0 kg*m/s - 5.25 kg*m/s = -5.25 kg*m/s
3. Calculate the Force
* Impulse = Force * Time
* Force = Impulse / Time
* Force = (-5.25 kg*m/s) / (0.02 s) = -262.5 N
The negative sign indicates that the force is in the opposite direction of the baseball's initial motion (i.e., the glove is slowing the ball down).
Therefore, the force exerted by the glove on the baseball is 262.5 Newtons.
