you are given:
initial speed, u = 0
final speed, v = 220
acceleration = (v-u)/t ===> t= time taken for the plane to reach final velocity(in hours)
then you use the formula:
displacement, s = u.t + (1/2).a.t^2
Suppose a particular jet needs to attain a speed of 220 mph to take off. If it can accelerate from 0 to 220 mph in 30 seconds, how long must the runway be? Assume constant acceleration. Note: 1 mph = 22/15 ft/sec.
need help mainly with how to set this one up and i think from there i could figure out the rest, thanks
