If two trucks have the same mass, but truck A is traveling 15 km/h, and truck B is traveling 30 km/h, what statement is true? Qu

estion 2 options: Truck A has greater kinetic energy. Truck B has less kinetic energy. Truck B will have a greater stopping distance. Truck A will have a greater stopping distance.

Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.

The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.

From the following expression

Speed = Distance/Time

Distance = Speed*Time

More on the kinetic Energy

Following from the given problem truck B will also have more kinetic energy because it velocity is more

Formula

KE= 1/2mv^2

Hence the more the velocity for a constant mass the greater the Kinetic energy
