Question

A 2000kg car is sitting at rest in a parking lot. A bike and rider with total mass of 60 kg is

travelling along a road at 10 km/h. Which system has more inertia? Why?​

Answer 1

Answer:

ok plz put me on brainlist

Explanation:

The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.

Answer 2

The car system has more inertia.

The property of a body that makes it oppose any force that would cause a change in its motion is known as inertia.

• A moving body or a body at rest oppose force which might cause acceleration.
• The inertia of the body is the direct measurement of mass.
• It helps in governing the resistance of the action of force.
• As the above two systems the car has greater mass than the bike.
• Hence, it has greater inertia
