All the fire alarms in the house went off tonight (probably triggered by one of them), but there was no sign of fire or smoke. What could it be? :)
Vertical initial speed v 25.7 sine38.7solve for v Maximum height h v^2/2g where g is gravitational constant, 9.81,solve for h Time to reach maximum height t v/g..solve for t Horizontal velocity (which is constant) V 25.7cosine38.7..solve for V Horizontal distance (how far hose from building) d V x t.solve for d
If you are driving slowly across them, you are not damaging anything. You likely are hitting stuff on the street that is doing more damage. Cross them at a slight angle so you are not beating both front wheels at the same time.
