Four vehicles are traveling on the same road. which vehicle most likely has the greatest kinetic energy? a compact car traveling at a velocity of 10 m/s a pickup truck traveling at a velocity of 25 m/s a minivan traveling at a velocity of 10 m/s a motorcycle traveling at a velocity of 25 m/s

a pickup truck traveling at a velocity of 25 m/s

Explanation:

The kinetic energy of an object is given by:

where

m is the object's mass

v is its speed

Therefore, the larger the mass and the speed of the object, the greater its kinetic energy.

Among the choices given, the object with larger mass is for sure the pickup truck; also, it is the object with larger speed (25 m/s), therefore it must be also the object with greater kinetic energy.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
