A2000 kg truck traveling north at 34 km/h turns east and accelerates to 58 km/h. (a) what is the change in the truck's kinetic energy? (b) what is the magnitude of the change in its momentum?

Explanation:

It is given that,

Mass of the truck, m = 2000 kg

Initial velocity of the truck, u = 34 km/h = 9.44 m/s

Final velocity of the truck, v = 58 km/h = 16.11 m/s

(a) Change in truck's kinetic energy,

(b) Change in momentum of the truck,

Hence, this is the required solution.
