Question

A 1740 kg car has just passed a diner. the closest the car came to the diner was r = 36.5 m, but the car has driven another x = 42.7 m in the 3.05 a elapsed since then. if the car travels at constant speed, what is the current magnitude l of the angular momentum of the car about the diner?

Answer 1

The current magnitude of the angular momentum of the car about the diner can be calculated using the formula L = mvr, where L is the angular momentum, m is the mass of the car, v is the velocity of the car, and r is the distance between the car and the diner.

Step-by-step explanation:

The angular momentum of the car about the diner can be calculated using the formula:

L = mvr

Where L is the angular momentum, m is the mass of the car, v is the velocity of the car, and r is the distance between the car and the diner.

In this case, the car has driven an additional distance x = 42.7 m, so the total distance between the car and the diner is r + x = 36.5 m + 42.7 m = 79.2 m.

The current magnitude of the angular momentum of the car can be calculated as:

L = (1740 kg)(v)(79.2 m)
