A 2220 kg truck traveling north at 40 km/h turns east and accelerates to 63 km/h. What is the change in the truck's kinetic energy? What is the magnitude of the change in its momentum?
a) ΔKE = 0 J, Δp = 0 kg·m/s
b) ΔKE = 194 kJ, Δp = 7.48 × 10⁴ kg·m/s
c) ΔKE = 108 kJ, Δp = 4.44 × 10⁴ kg·m/s
d) ΔKE = 86 kJ, Δp = 3.33 × 10⁴ kg·m/s
