Question

Help please:A boy weighing 30 kg rides a scooter. The total kinetic energy of the boy and the scooter is 437.6 J. Determine the speed at which the boy moves if the mass of the scooter is 5kg?​

Answer 1

Answer:

5 m/s

Explanation:

Mass of the boy + scooter system =  35 kg

Kinetic Energy =  437.6 J

437.6 = $\frac{1}{2} 35 {v}^2$

25.0057143 = $v^{2}$

v = 5 m/s
