Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

12. How much force would a car's tires need to provide to accelerate an 1800 kg car at a rate of 4.0 m/s²?
Your answer:
39 N
450 N
O 1800 N
O 7200 N

Expert Solution

Step 1

Given that,

The mass of a car, m = 1800 kg

Acceleration of the car, a = 4 m/s²

We need to find the force a car's tires need to accelerate. The expression for the force acting by the car is given by :

$F = m a$ ...(1)

Where

m is mass and a is the acceleration
