Incorrect 36.60 Incorrect16.0 kg and m₂ (a) Objects with masses m₁ 9.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m₂ falls 1.00 m in 1.46 s, determine the coefficient of kinetic friction between m₁ and the table. m₁ = m₂ = (b) What If? What would the minimum value of the coefficient of static friction need to be for the system not to move when released from rest?A 10.0 kg mass hangs from a rope, as shown in the figure. The rope passes over a fixed pulley, then under a movable pulley, and is attached to the ceiling as shown. The movable pulley has a mass m attached to it and moves at a constant speed. Find the tension in the rope. Assume that the masses of the pulleys are negligible.
- answer c pleaseA person on a sled starts descending from the highest point of a snowy slope with a 30º inclination and 150 m in length. The combined mass of the person and the sled is 90 kg. At the end of the slope, they continue moving on a horizontal track until they stop. The coefficient of friction between the sled and the snow is \( \mu = 0.18 \) in both cases. 1. Draw the forces acting on the sled in each section. 2. Calculate the mechanical energy dissipated due to friction on the inclined section. 3. With what speed does it reach the end of the slope? 4. What distance does the sled travel on the horizontal plane before stopping?Answer the question correctly. Thank you!
