I have questions about circular motion. help would be really appreciated

AI Thread Summary
The discussion focuses on questions related to circular motion, specifically the forces involved in scenarios like a washing machine's spin cycle and a car turning. The force acting on clothes during the spin cycle is attributed to the walls of the tub. When a car turns right, the force acting on a passenger is due to inertia. Additionally, when tossing a ball in a car that is turning, the ball will land beside the passenger, toward the outside of the curve. Understanding these principles of circular motion is essential for grasping the underlying physics.

i have questions about circular motion. help would be really appreciated!

What exerts the force that acts on the clothes in the spin cycle of a washing machine?
a. the walls of the tub
b. the motor in the washing machine

You are sitting in the back seat of a car going around a curve to the right. What exerts this force acting on you?
a. the car's engine
b. inertia
c. the seat of the car

Imagine that you are sitting in a car tossing a ball straight up into the air. If the car rounds a curve at constant speed, where will the ball land?
a. The ball will land beside you, toward the inside of the curve.
b. The ball will land beside you, toward the outside of the curve.
c. The ball will land behind your hand.anyone have any ideas?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
