Question

A 2 kg ball is thrown upward with a velocity of 15 m/s. What is the kinetic energy of the ball as it is being thrown?

Answer 1

KE=1/2 m v^2
KE= .5 x 2kg x 15m/s to the 2nd power
KE=225 km/s

Answer 2

Answer:

Kinetic energy = 225 J

Explanation:

As we know that kinetic energy is given as

$KE = \frac{1}{2}mv^2$

now here we know that

m = 2 kg

v = 15 m/s

now from above formula we know

$KE = \frac{1}{2}(2)(15)^2$

now we have

$KE = 225 J$

so kinetic energy of the moving ball is 225 J
