You are going sledding with your little cousins during a well-earned break. you push your 23 kg cousin so that they have a speed of 6 m/s at the top of the hill that is 17 m tall. what is the kinetic energy of your cousin at the top of the hill (after you push)? (in j)

kinetic energy = 414 J

Explanation:

given data

mass = 23 kg  

speed = 6 m/s  

height = 17 m    

to find out

kinetic energy

solution

we get kinetic energy that is express as

kinetic energy = 0.5 × m × v²    1

here m is mass and v is speed so

put here value we get kinetic energy

kinetic energy = 0.5 × 23 × 6²

kinetic energy = 414 J

414 J

Explanation:

mass, m = 23 kg

velocity, v = 6 m/s

Kinetic energy is given by

K = 0.5 mv²

K = 0.5 x 23 x 6 x 6

K = 414 J

Thus, the kinetic energy is 414 J.
