Answer:
The momentum of an object is defined as the product of its mass and velocity. In this case, we can calculate the momentum of the car by multiplying its mass by its velocity.
However, the problem statement only provides the weight of the car, which is a measure of the force of gravity acting on the car due to its mass. The mass of the car can be calculated using the formula:
weight = mass x gravity
where gravity is the acceleration due to gravity. Rearranging this formula, we get:
mass = weight / gravity
Substituting the given values of weight = 3500 N and gravity = 9.8 m/s^2, we get:
mass = 3500 N / 9.8 m/s^2 = 357.1 kg
Now that we know the mass of the car, we can calculate its momentum using the formula:
momentum = mass x velocity
Substituting the given value of velocity = 35 m/s and the calculated value of mass = 357.1 kg, we get:
momentum = 357.1 kg x 35 m/s = 12,500 kg⋅m/s
Therefore, the momentum of the car is 12,500 kg⋅m/s.
