An object is thrown straight up from ground level with a speed of 50 m/s.If g = 10 m/s² its distance above ground level 6.0 s later is: A)0.00 m B)270 m C)330 m D)480 m E)none of these

Question

The distance above ground level after 6.0 s can be calculated using the formula for the position of an object under uniform acceleration: $s = ut + \frac{1}{2}at^2$, where $s$ is the distance, $u$ is the initial velocity, $t$ is the time, and $a$ is the acceleration (in this case, $a = -g = -10 \, \text{m/s}^2$ because gravity is acting in the opposite direction to the motion). Plugging in the values: $s = 50 \times 6 - \frac{1}{2} \times 10 \times 6^2 = 300 - 180 = 120 \, \text{m}$. Since 120 m is not listed among the options, the correct answer is E) none of these.
