I'm confuse by what the question is asking as far as the conversion (km/hr/s). Can any please help me?
A jumbo jet must reach a speed of 240 km/hr on the runway for takeoff. What is the minimum constant acceleration (in km/hr/s) needed for takeoff from a 1.34 km runway? (3 sig fig)
a=vf^2/2(Δx)
a=(240 km/hr)^2/2(1.34 km) = (57600 km^2/hr^2) / (2.68 km) = 21492.53731
