The simple machine in a catapult is a lever, although there can alos be a pulley included. Because t<span>he load and effort are on opposite sides of the fulcrum, they move in opposite directions. This is why catapults can launch objects.</span>
A high tide means when the water has risen and is higher up(closer to high up land). Low tide is when it’s receded
Let v = the running speed
After running at constant speed for 26 min, the distance traveled is
d = (v m/min)*(26 min) = 26v m
Because there are 1500 m to go, the distance traveled is
10000 - 1500 = 8500 m
The running speed is
v = (8500 m)/(26 min) = 326.9 m/min
In km/h, the speed is
v = (0.3269 km/min)*(60 min/h) = 19.6 km/h
Answer: The running speed is 19.6 km/h
