A dog initially running at a speed of 2 m/s accelerates at constant rate of 1.5 m/s2 for 5 s.Calculate:(1) distance covered by it from start (2) the final velocity of the dog?
A dog initially running at a speed of 2 m/s accelerates at constant rate of 1.5 m/s2 for 5 s.Calculate:(1) distance covered by it from start (2) the final velocity of the dog?
Solution: We know the formula,
where v is final velocity,
a
Here we get,
Hence,(2) Final velocity of the dog is
And the another formula to determine the covered distance is
Hence,here displacement is
(1) Total distance covered is
