Here's an interesting one. Consider a sled .. a rocket cart which is used to study acceleration and deceleration effects. (Yes that's a real thing). One way of stopping such a sled is to put a scoop on the front deflecting water upwards as in the image below: Water 60° Assume scoop is 20 cm wide (into page), and dips 8 cm into the water (d = 8 cm). The sled is 1000 kg and initially traveling at 100 m/s. What is the initial deceleration .. remember F = ma.
