An object undergoes an acceleration of 10 m/s2 starting from rest. Find the distance travelled in 5 seconds.

Solution
Here comma space A c c e l e r a t i o n comma space straight a space equals space 10 space straight m divided by straight s squared Initial space velocity comma space straight u space equals space 0 T i m e space o f space t r a v e l comma space space straight t space equals space 5 space straight s Distance space covered space in space 5 space sec comma space straight s space equals space ? U sin g space t h e space f o r m u l a comma straight s space equals space ut plus 1 half at squared space equals space 0 space plus space 1 half space cross times space 10 space cross times space 5 squared space equals space 125 space straight m therefore space space space Distance space travelled space by space the space object space space equals space 125 space straight m. space
