Question

Marcus Aurelius runs and jumps off a table horizontally from a height of 2m with a speed of 7.5 m/s. How far will he travel before he reaches the ground?

Answer 1

`4.8 m`

Explanation:

As,during running his final velocity was directed horizontally,we can say that not only he will go down but also move forwards from the table,

Considering,for his vertical motion only,we can say,if it takes time `t` to reach the ground,then we can write,

`2= 1/2 g t^2` (using, `s=1/2 g t^2`)

So, `t=0.64 s`

So,in this time if he moves forward by distance `x` then we can say, `x=7.5*t=7.5*0.64=4.8 m`
