Aturtle is traveling at 1 m/s and is slowing down at a constant rate. it stops after three seconds. what is the acceleration

Equation of motion is given by:

v=u+at              ......[1]

where,

v represents the final velocity is measured in m/s

u represents the initial velocity is measured in m/s

a represents the acceleration is measured in    and

t represents the time in second

As per the statement: A turtle is traveling at 1 m/s and is slowing down at a constant rate. it stops after three seconds.

⇒ Initial velocity(u) = 1 m/s ,  final velocity(v) = 0 and t = 3 seconds.

Substitute the given values in [1] to solve for a;

Subtract 1 from both sides,

0 -1 = 1+ 3a  -1

Simplify:

-1 = 3a

Divide by 3 both sides we get;

Therefore, the acceleration is,

in 4 days he will run   12/14
