Answer: Truck 2, because it has a larger mass than truck 1 (and the same velocity)
Explanation:
We can write the kinetic energy of an object with mass M and velocity V as:
K = (M/2)*V^2
Let's calculate the kinetic energy for each truck:
Now, we can see that both trucks move at the same velocity, but truck 1 has a mass of 5000 pounds, while truck 2 has also a mass of 5000 pounds and an extra of 900 pounds.
Then the total mass of truck 2 is 5000 pounds + 900 pounds = 5900 pounds.
Then both trucks have the same velocity, and truck 2 has a larger mass than truck 1, this implies that truck 2 will have a larger kinetic energy than truck 1.
Answer:
The mass of the object is 15.0 kg
The weight of the object is 147.15 N
Explanation:
The mass of the object is the quantity of matter contained in the object or the measure of the its property of inertia.
The mass is constant through out the universe
The mass of the object is given as 15.0 kg
The weight of the object is the force of attraction of the Earth on the object
The weight is dependent on the interacting objects.
The weight of the object = The mass of the object × Acceleration due to gravity
Where;
The acceleration due to gravity, g = 9.81 m/s²
∴ The weight of the object = 15.0 kg × 9.81 m/s²= 147.15 N
The weight of the object = 147.15 N
