Truck 1 is a 500-kg object traveling at a velocity of 35 m/s, and truck 2, is a 400-kg object traveling at a velocity of 40 m/s. Which object has a larger kinetic energy?
Truck 1
Truck 2
The two trucks have the same kinetic energy
Not enough info is provided
A truck has 2 times the mass of yet another truck, and is moving at the same velocity. If K1 and K2 refer to the two trucks respectively, it is correct to say that
K1=4K2
K1=3K2
K1=2K2
K1=K2
