Which has a greater momentum and greater kinetic energy-a truck with a mass of 3530 kg moving at a speed of 21 m/s or a car with a mass of
1620 kg moving at a speed of 54 m/s? Answers below are given in the
form: greater momentum, greater kinetic energy.

the car has greater momentum.

the car has greater kinetic energy.

Explanation:

FOR MOMENTUM:

Momentum is given as the product of mass and velocity of an object:

where,

P = momentum

m = mass

v = velocity

For Truck:

For Car:

Therefore, car has greater momentum.

FOR KINETIC ENERGY:

Kinetic Energy is given as:

where,

K.E = Kinetic Energy

m = mass

v = velocity

For Truck:

For Car:

Therefore, car has greater kinetic energy.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
