Asports car and a minivan run out of gas and are pushed to the side of the road. which is easier to push, and why?
a. the minivan, because it has more mass and therefore more inertia
b. the minivan, because it has less mass and therefore less inertia
c. the sports car, because it has more mass and therefore more inertia
d. the sports car, because it has less mass and therefore less inertia

Answer from: cfnewton09

The correct answer to the question is : D) The sports car, because it has less mass and therefore more inertia.

EXPLANATION:

From Newton's second law of motion, we know that the total amount of external force that acts on a body is equal to the product of mass with acceleration of the body.

Mathematically F = ma.

Here, m is the mass and a is the acceleration of the body.

Hence, more is the mass of a body, more force is required to change its state.

As per the question, we have a sports car and a minivan.

The mass of the sports car is less than the mass of the minivan.

Hence, it is easier to push a sports car as compared to the minivan.

Answer from: mashedpotatoes28

The answer is:

D. the sports car, because it has less mass and therefore less inertia

Explanation :

1)Because the car which has the lower mass will be easy to push.

2)and when the sports car is less weight than the minivan, then it will be definitely easy to push when both run out of gas.

-when the force equals the product of mass and acceleration. Therefore, lower the mass, the less the force need to be applied to push.

-when force is directly proportional to the mass of the object.

F = m a

when F is the Force

and m is the mass

and a is the acceleration

The objects do not reach terminal velocity there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
