a 1490 kg car has just passed a diner. the closest the car came to the diner was r=40.5, but the car has driven another x=30.7 m in the 2.25 s elapsed since then. If the car travels at constant speed, what is the current magnitude of the angular momentum of the car about the diner?
30.27 m in 2.25 s
so speed of car = 30.27/2.25 = 13.45 m/s
so angular momentum = r*m*v= 40.5*1490*13.45 = 811640.35

A 1540 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 = 32.7 m in the 2.25 s elapsed since then. If the car travels at constant speed, what is the current magnitude of the angular momentum of the car about the diner?
A 1840 kg car has just passed a diner. The closest the car came to the diner was R = 24.5 m, but the car has driven another x = 38.7 m in the 2.45 s elapsed since then. If the car travels at constant speed, what is the current magnitude of the angular momentum of the car about the diner?
A 1840 kg car has just passed a diner. The closest the car came to the diner was R = 32.5 m, but the car has driven another x = 40.7 m in the 2.05 s elapsed since then. If the car travels at constant speed, what is the current magnitude of the angular momentum of the car about the diner?
A 1200-kg car rounds a circular turn of radius R, toward the right, moving at a constant speed of 10.0 m/s on a horizontal road. Its angular momentum about the center of the turn has magnitude 2.00 - 108kg. ma. a) (4p) What is the direction of the angular momentum of the car? b) (6p) What is the radius of the turn?
A 1450-kg car rounds a circular turn of radius 140 m, toward the left, on a horizontal road. Its angular momentum about the center of the turn has magnitude 3.16×106kg⋅m2/s. What is the speed of the car?
1. IP A turntable with a moment of inertia of 5.2×10−3 kg⋅m2 rotates freely with an angular speed of 3313rpm . Riding on the rim of the turntable, 19 cm from the center, is a cute, 32 g mouse.A) If the mouse walks to the center of the turntable, will the turntable rotate faster, slower, or at the same rate? (Answer is Slower)B) Explain.C) Calculate the angular speed of the turntable when the mouse reaches the center.2. One elevator arrangement...
A thick walled cylinder has a light string
wrapped around its outer radius and rotates
about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.
When the system is released from rest the mass slides down the ramp
a distance of 1.80...
Suppose a small compact car with a mass of 1000 kg is traveling
north on Morewood Avenue at a speed of 15 m/s. At the intersection
of Morewood and Fifth Avenues, it collides with a truck with a mass
of 2000 kgthat is traveling east on Fifth Avenue at 10 m/s. It’s
now 2 seconds after the collision has occurred. Fortunately, all
occupants were wearing seat belts and there were no injuries, but
the two vehicles became thoroughly tangled and...
plz answer all four questions, thanks!
