Question

what is the kinetic energy of a 1 kilogram ball is thrown into the air with an initial velocity of 3 m/sec

Answer 1

Data:
m (mass) = 1 Kg
s (speed) = 3 m/s
Kinetic energy = ? (Joule)


Formula (Kinetic energy)

`E_(k) = (m*s^2)/(2)`

Solving:

`E_(k) = (m*s^2)/(2)`

`E_(k) = (1*3^2)/(2)`

`E_(k) = (1*9)/(2)`

`E_(k) = (9)/(2)`

`\boxed{\boxed{E_(k) = 4.5\:J}}\end{array}}\qquad\quad\checkmark`
