This part of the lab is mostty analytical. Consider a 250-gram cart loaded with additional 250 grams (for a total mass of 500 grams) sitting on a frictionless track and having zero initial velocity. A string passed over a pulley attached to one end of the track connects the cart with a vertical 50-gram mass hanger. If you arrange this situation in the Virtuallabs environment and keep the track horizontal, you will notice that the cart-hanger system is moving with some constant acceleration. Your objective is to apply the Newton's Second Law of motion In order to calculate to what angle (let's call it "critical") should the track be tilted (made into an incline) to prevent the cart from moving in either direction. In the the experimental worksheet include the free body diagrams for the cart on the tilted track and the hanger, derive the equation for the "critical" angle and calculate its value.

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
