Two cars are driving down Sutter Avenue. Car 1 has a mass of 90kg and is traveling 80 miles in one hour. Car 2 has a mass of 120kg and is traveling 80 miles in one hour.
Part A:Compare the motion of each car.
PartB:The engine applies the same amount of force in each car. Which car would have a greater acceleration? How do you know?
i want the answer
Car 1 is going faster because it has a lesser mass. Btw I am in 6th grade.
Part A:
To compare the motion of each car, we need to consider their mass, speed, and distance traveled.
Car 1 has a mass of 90kg and is traveling 80 miles in one hour.
Car 2 has a mass of 120kg and is also traveling 80 miles in one hour.
Since both cars are traveling the same distance in the same amount of time, we can say that they have the same average speed. However, their masses are different.
Part B:
To determine which car would have a greater acceleration, we need to consider the force applied by the engine.
The force is given by the equation F = ma, where F is the force, m is the mass, and a is the acceleration.
Since the problem states that the engine applies the same amount of force in each car, we can assume that the force values are equal.
By rearranging the equation F = ma, we get a = F/m. This means that the acceleration is inversely proportional to the mass. Therefore, the car with the smaller mass will have a greater acceleration.
In this case, Car 1 has a mass of 90kg and Car 2 has a mass of 120kg. Since Car 1 has the smaller mass, it will have a greater acceleration compared to Car 2.
So, Car 1 would have a greater acceleration because it has a smaller mass.
