an airplane accelerates down a runway at 3.20 m/s for 32.8s until is finally lifts off the ground. determine the distance travelled before takeoff.

Sagot :

S=ut+1/2at^2    s=distance travelled=?    u=intial velocity=3.2m/s  a=accelaration due to gravity=9.8m/s^2    t=time=32.8s    then s=3.2x32.8 +1/2 9.8 32.8x32.8           s=104.96+4.9x32.8x32.8 s=104,96+5271.616=5376.576m
