Question

An object is dropped from the height of 19.6m. Draw the displacement -time graph for time when object reach the ground. Also find velocity of the object when it you touches the ground​

Answer 1

Answer:

19.6 m/s

Explanation:

2as = v² - u²

2 × 9.8 × 19.6 = v² - 0²

v² = 384.16

v = 19.6 ms⁻¹

Answer 2

Answer:

final velocity is 19.6m/s

and displacement time graph will be similar to y=x^2 graph
