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.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

the answer is a)
