Question

A basketball player jumps straight up with a speed of 14 m/s. How high did the player jump?

Answer 1

The basketball player jumped 10 m high.

Step-by-step explanation:

Vertical Launch Upwards

In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.

If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

`\displaystyle h_m=(v_o^2)/(2g)`

The basketball player jumps up with a speed of vo=14 m/s. The maximum height is:

`\displaystyle h_m=(14^2)/(2*9.8)`

`\displaystyle h_m=(196)/(19.6)=10`

The basketball player jumped 10 m high.
