Question

3.) If Lebron James has a vertical leap of +1.35 m. then what is his takeoff speed7 For this

Answer 1

D, I hoped that helped you

Answer 2

The answer is 5.14 m/s is the answer. None of the options were correct.

Option: d

Explanation:

This is a question of kinematics. In the given question, acceleration $a=-9.8 \mathrm{m} / \mathrm{s}^{2}$

Vertical loop of James is s = 1.35 m  

Final velocity of James is v = 0  

We are required to find the take-off speed of James i.e., using the second equation of motion,  

v² = u² + 2as

$0-u^{2}=2 \times(-9.8) \times 1.35$

$-\mathrm{u}^{2}=-19.6 \times 1.35$

$\mathrm{u}^{2}=26.46$

u = 5.14 m/s (approx)  

So, the answer is none of the choices.
