(3) 10.1 second Using equation of motion 500 = (0.5)(9.81)t^2. Rearranging, t = sqrt(1000/9.81) = 10.1s

The time required for an object starting from rest to fall freely 500. meters near Earth’s is 10.1 s

Without air resistance Distance  =  1/2 g T²

500 m  =  (1/2) (9.8 m/s²) (T²)

 500 m  =  (4.9 m/s²) (T²)

Divide each side by   (4.9 m/s²)  

T²  =  (500 m) / (4.9 m/s²)

= 102.04 s²

T  =  √ (102.04 s²)

T =  10.1 seconds
