3.) if lebron james has a vertical leap of +1.35 m. then what is his takeoff speed7 for this
problem, the value of a, = -9.8 m/s2
a.) 5.17 m/s2
b.) 6.9 m/s
c.) 4.3 s
d.) neither of these choices

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

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

u = 5.14 m/s (approx)  

So, the answer is none of the choices.

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
