Question

A car balls of the edge and drop to the ground in 0.5 second is equal to 10 metre per second square what is average speed during 0.5 second​

Answer 1

Hey!

given , 

u=0

t=0.5s

b) average speed=total distance/total time

so, 

s=ut+1/2gt^2

s=0*0.5+1/2*10^2

s=50m

so,

average speed=50/0.5=100ms-1
