Answer:

The driveway pushing up on the car

Explanation:

A reaction force is the force that acts upward on an object resting on a particular surface to balance the effect of the weight of the object which acts downward. For this 2-ton car parked on a driveway, the reaction from the floor of the driveway acts upward on the car to balance the downward force of the weight of the car since in every action, there is equal and opposite reaction. By this force balancing, the car will neither move up nor sink down to the ground as long as it is parked on the driveway.

Answer:

6666.67 Newtons

Explanation:

The formula F=ma (force is equal to mass multiplied by acceleration) can be used to calculate the answer to this question.

In this case:

  • mass= 0.1mg= 1*10^-7 kg
  • velocity= 4.00*10^3 m/s
  • time= 6.00*10^-8 s

Using velocity and time, acceleration can be calculated as:

  • a= 6.667*10^10 m/s²

Substituting these values into the formula F=ma, the answer is:

  • F= (1*10^-7)kg * (6.667*10^10) m/s²
  • F= 6666.67 Newtons of force

Sergeu [11.5K]

Answer:

When you jump off a train, you jump off a certain height and your downwards (vertical) velocity is zero. But your forward (horizontal) velocity is not. You will hit the ground on split second with your horizontal velocity practically the same as the train.

Explanation:

you be in serious injury.
