Problem

An object moving in a straight line with uniform acceleration covers

15\,\text{m}

in the

5^{\text{th}}

second of its motion and

21\,\text{m}

in the

7^{\text{th}}

second of its motion. a. (i) Show that the acceleration of the object is uniform by suitable calculations. b. (ii) Determine the values of the initial velocity and the uniform acceleration. c. (iii) Using the values found, find the velocity of the object at the end of the

10^{\text{th}}

second.
