(a) A car with a mass of 950 kg is moving to the right with a constant speed of 1.45 m/s. What is the total force on the car?
(b) What is the total force on the car if it is moving to the left?
zero because F = m a = m*0.00
To find the total force on the car, we need to use Newton's second law of motion, which states that the force on an object is equal to its mass multiplied by its acceleration.
(a) The car is moving to the right with a constant speed, which means its acceleration is zero. Therefore, we can calculate the total force on the car as:
Force = Mass x Acceleration
= 950 kg x 0 m/s^2
= 0 Newtons
So the total force on the car is 0 Newtons.
(b) If the car is moving to the left, we need to consider the direction of the force. The force will act in the opposite direction to the car's motion, so it will be to the right.
Since the car is still moving at a constant speed, the acceleration is still zero. Using the same formula as before, we can calculate the force:
Force = Mass x Acceleration
= 950 kg x 0 m/s^2
= 0 Newtons
So, the total force on the car, even when it is moving to the left, is still 0 Newtons.
