Firefighter hose must be fired from a distance because of some obstacles if the water spiller city is 30 m/s angled 45 degrees reaches the source of the fire in 3.5 s, how far is the firefighter from the fire
Answered by R_scott
"spiller city" ... ? ... velocity ?

horizontal component of velocity ... cos(45ยบ) * 30 m/s = vh

distance = vh * 3.5 s
