Keyboard Cat usually enjoys playing Chopin. Frederic Chopin played very delicately and Keyboard Cat has an ear for nuance and sensitivity. But she is growing tired of the style. Recently, Keyboard Cat decided to venture into the world of Liszt. Liszt was a hard hitter. He was known as "The Breaker of Pianos" because he played so loud, with such boisterous emotion.
In order to match Liszt's piano playing style, the internet famous feline must press her piano keys forcefully. For one of these loud notes, on average, her paw slows down from -1.50 m/s (just as it comes into contact with the key) to 0.00 m/s (once the key is fully pressed) over a time interval of just 6.3 milliseconds. Assuming Keyboard Cat's paw has a mass of 0.13 kg, what will be the net force (in Newtons) acting on Keyboard Cat's paw during one of these passionate key strikes?
Hint: Be mindful of units!
Round to the nearest hundredth.
