Explanation / Answer

Here ,

m = 5.7 Kg

Vox = 6 m/s

Voy = -2 m/s

a) kinetic energy of the object = 0.50 * m * (Vox^2 + Voy^2)

kinetic energy of the object = 0.50 * 5.7 * (6^2 + 2^2)

kinetic energy of the object = 114 J

b)

final kinetic energy = 0.50 * m * (Vox^2 + Voy^2)

final kinetic energy = 0.50 * 5.7 * (8.5^2 + 5^2)

final kinetic energy = 277 J

change in kinetic energy = 277 - 114

change in kinetic energy = 163 J

the change in kinetic energy is 163 J
