  An object is thrown vertically upwards and reaches a height of 10 m. Find (i) the velocity with which it was thrown up. (ii) time taken by it to reach the highest point. (g= 9.8 m/s2)

Answer:

                  Height of an object, h =10 m Acceleration due to gravity g = -9.8 m/s2 (negative sign in taken for upward motion)     (2) Final velocity, v = 0 (i)                                 (ii)Time taken, (1)
