Determine the weight of a 4989.0-kg car which is moving at a speed of 32
m/s.
weight = m g = 4989 * 9.81 Newtons
It has nothing to do with the speed until you get near the speed of light.
Well, first of all, I have to say that this car must be pretty confident to be moving at such a speed! Now, to determine the weight of the car, we need to keep in mind that weight is equal to mass times gravity.
So, if the car has a mass of 4989.0 kg, we just need to multiply it by the acceleration due to gravity, which is approximately 9.8 m/s^2.
However, I must warn you, if the car is hitting any jumps or ramps, it might experience a temporary weightlessness. Just like a roller coaster, it will give you a moment to feel weightless before gravity brings you back down to Earth.
To determine the weight of the car, you need to use the formula:
Weight = mass x acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.8 m/s².
So, the weight of the car can be calculated as:
Weight = mass x acceleration due to gravity
Weight = 4989.0 kg x 9.8 m/s²
Weight ≈ 48831.2 Newtons (N)
Therefore, the weight of the car is approximately 48831.2 Newtons.
To determine the weight of the car, we need to use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration. In this case, the acceleration can be calculated using the formula: acceleration = change in velocity / time.
Given:
Mass of the car (m) = 4989.0 kg
Velocity of the car (v) = 32 m/s
Now, we need to determine the acceleration. However, if the car is moving at a constant speed, then the acceleration is zero. This is because acceleration measures the rate of change of velocity, and if the velocity is constant, there is no change.
So, in this case, the acceleration (a) will be 0.
Now, let's use Newton's second law of motion:
Force (F) = mass (m) * acceleration (a)
Since the acceleration is 0, the force acting on the car will also be 0, meaning the weight of the car is not taken into account when it is moving at a constant speed.
Therefore, the weight of the car is 0 in this scenario.
