I need help in solving this.And I need to know how.Please help and thank you.
Velocity = (g*t) m/sec. (9.8 x 4) = 39.2m/sec.
Ok. Gravity has a acceleration of 9.8 meters per second but many people round off to 10 meters per second. The formula is 10 m/s square. So at the first second is 10, at the second is 20, at the third is 30, at the four it os 40. Every second the velocity increases 10 meters per second. If the inicial speed is 10 then at the four you will get 50 meters per second velocity. You multiply.
