Consider a pair of masses m1 and m2 connected by a non-stretchable string that runs over a frictionless pulley as shown on the figure on the right. If the coefficient of the kinetic friction between m1 and on the horizontal surface on which it initially rest is μk, find its resulting acceleration magnitude in terms of m1, m2, and μk, when the system is released. Assume that air resistance is negligible and m2 > μk m1. Show the complete and thorough solution in a clean paper
Given the following information, how would you find the acceleration of the two block system?
"Two blocks with masses m1 and m2 are connected by a massless string and sliding down a plane inclined at an angle ?, as shown in the figure below. The kinetic coefficient of friction between block m1 and the inclined plane is ?2, and ?3 for block m2. You can assume that the acceleration due to gravity is given as ?."
A parcel is connected to a flying drone as illustrated above. Note that the coordinate system is givenwith +y pointed in the upwards direction. Holding the parcel, the drone takes off moving straight upwith a velocity of 8.40. m/s. Note that, as usual, y = 0 at the ground.After 8.00 s, the drone accidentally releases the parcel! The parcel is in “freefall” immediately after it isreleased, as defined in Lecture 7. Assume that the magnitude of the acceleration, g = 9.81 m/s2, and thatthe drone continues with the same velocity after releasing the parcel. Ignore the effects of air-resistance
a) What is the acceleration of the drone as it travels upwards?b) What is the velocity of the parcel immediately after it is released?c) What is the acceleration of the parcel immediately after it is released? (Remember accelerationis a vector and the sign is important (i.e. “+” for pointing up, or “-” for pointing down.d) What is the velocity and acceleration of the parcel when it reaches its maximum…

- Given the following information, how would you find the magnitude of the acceleration of the system. Express youranswer in terms of known quantities such as m1, m2, theta, k, xs, x0, and g. "A ball of mass m1 and block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure below. The block lies on a smooth plane inclined at an angle 'theta'. The ball is attached to a spring whose spring constant is k and equilibrium position x0. The spring is then stretched so it measures a length xs. You may use the fact that the force due to a spring is opposite the stretch and equal to −kΔxstretch. The system is then released. You can assume that the acceleration due to gravity is given as g, and use the consistent coordinate system specified for each object."arrow_forwardEach of the systems shown is initially at rest.
