Question

The kinetic energy K (in joules) of a falling apple is represented by K=v22, where v is the speed of the apple (in meters per second). How fast is the apple traveling when the kinetic energy is 32 joules? The apple is traveling at meters per second.

Answer 1

Answer: 1.455 m/s

Step-by-step explanation: k = 22v defines the motion of falling apple.

With k as kinetic energy and v as velocity.

We are to find the value of v at k = 32 joules

32 = 22v

v = 32/ 22

v = 1.455 m/s
