Homework Statement
A car with mass of 2t, from starting point travels a distance of 100m for 10s. How much is the pulling force of the car?
Which means that:
m=2t=2000kg
s=100m
t=10s
F-pulling=?
How to find it? :P
To calculate the pulling force, we use the formula: Force = Mass * Acceleration. In this case, the mass of the car is 2 tonnes (2000 kg) and the acceleration is 100m/10s = 10m/s^2. Therefore, the pulling force is 2000kg * 10m/s^2 = 20,000 Newtons.
The unit of measurement for pulling force is Newtons (N). It is the amount of force required to accelerate a mass of 1 kg at a rate of 1 m/s^2.
Yes, the pulling force of a car can be negative. Negative force indicates that the car is slowing down, or decelerating. This can happen if there is a resistance force acting against the car's motion, such as friction or air resistance.
The mass of the car directly affects the pulling force. A heavier car will require more force to accelerate compared to a lighter car. This is because the mass is directly proportional to the force, according to Newton's Second Law of Motion.
No, the pulling force and the car's weight are not the same. Weight is a measurement of the force of gravity acting on an object, while pulling force is the amount of force required to accelerate the car. The weight of the car remains constant, but the pulling force can vary depending on the acceleration.
