An object was thrown upwards at a speed of 14 ms and flew 10 m high. Calculate the time taken by the object to reach the highest point.

1.63 s

1.43 s

1.53 s

1.33 s

To find the time taken by the object to reach its highest point:

- When an object is thrown upwards, at the highest point its velocity becomes zero.

- Use the equation: v = u + at

- v = final velocity = 0 (at highest point)

- u = initial velocity = 14 m/s

- a = acceleration due to gravity = -9.8 m/s² (since upwards throw)

- Substitute values:

0 = 14 + (-9.8)t

? 9.8t = 14

? t = 14 / 9.8 ˜ 1.43 s

- So, the closest and correct option is:

- Option 2: 1.43 s

Other Options:

- Option 1 (1.63 s), Option 3 (1.53 s), and Option 4 (1.33 s) do not match the calculation.
