The free fall body has gone 10m in the last 0.5s. Find the body speed at the moment of impact.

Correct answer:

v =  22.5 m/s

Step-by-step explanation:

t=0.5 s s=10 m  g=10 m/s2  s=21 g t1221 g (t1t)2 2 s/g=t12(t1t)2 2 s/g=t12t12+2 t t1t2 2 s/g+t2=2 t t1  t1=2 tt2+2 s/g=2 0.50.52+2 10/10=49=2.25 s  v=g t1=10 2.25=245 m/s=22.5 m/s
