A small economy car (low mass) and a limousine (high mass) are pushed from rest across a parking lot, equal distances with equal

Studentka2010 [4]

Answer:

The car that receives more kinetic energy is the small economy car.

Explanation:

K.E = 0.5*mv²

Where;

K.E is the kinetic Energy

M is the mass of an object

V is the velocity of the moving object

But F = m(v/t), from Newton's second law of motion

If equal forces were applied to the two cars, then the velocity of each car will be calculated as follows.

v = (Ft/m)

v² = (Ft/m)²

Substitute in the value of v² into Kinetic energy equation

K.E = 0.5*mv²

K.E = 0.5*m(Ft/m)² = (0.5*F²t²)/m

Also assuming equal distance, equal force and assuming equal time for both cars.

The above equation will reduce to, K.E = k/m

Where k = 0.5*F²t², which is equal in both cars.

Thus, Kinetic energy will depend only on the mass of each car.

From the above expression, Kinetic Energy received by each car is inversely proportional to the mass of the car.

A small economy car (low mass) will receive more kinetic energy while a limousine (high mass) car will receive less kinetic energy.

Therefore, the car that receives more kinetic energy is the small economy car.

A force is applied to an object at rest with a mass of 100 kg. The same force is applied to an object at rest with a mass of 1 k

Darya [45]

The object with a mass of 100 kg would move slower than the object with a mass of 1 kg. This is because a greater force is required to move the object with a mass of 100 kg compared to the object of 1 kg.

PtichkaEL [24]

Answer:

The distance from harvest mouse to the leaf is 4.74 m.

Explanation:

Given that,

Intensity = -10 dB

Distance = 1.5 m

We need to calculate the power of intensity
