Mass of the body does not affect the motion, all bodies fall at the same rate in vacuum. This rate on earth is approximately 9.8m/s^2. This means the speed increases by 9.8m/s every second. So the speed after t seconds is simply 9.8m/s^2\times\,t\,s=9.8t\,m/s

The speed after 5  seconds would be 9.8m/s^2\,\times\,5s=49m/s
