in 5 seconds, a car moving in a straight line increases it's speed from 50km/h to 65km/h, while a truck goes from rest to 15km/h in a straight line. which undergoes greater acceleration? what is the acceleration of each vehicle?

acceleration=(v2-v1)/time
Car: from 50 km/h INCREASED to 65 km/h, therefore;
65 km/h - 50 km/h = 15 km/h
Truck: from rest (which is 0 km/h) to 15 km/h, therefore;
0 km/h + 15 km/h
The car and the truck both have the same acceleration.
65 km/h - 50 km/h = 15 km/h
Truck: from rest (which is 0 km/h) to 15 km/h, therefore;
0 km/h + 15 km/h
The car and the truck both have the same acceleration.
