Two masses m₁ = 14 kg and m₂ = 15 kg are connected by a light inextensible string passing over a frictionless pulley. Find (a) acceleration of the system when released from rest, (b) the tension in the string, and (c) the speed of either mass after moving a distance of 2.0 m.

Please answer it within 30 minutes.I will upvote! Problem: With ball initial velocity of 40m/sCoefficient of kinetic friction between ball and ground is 0.110.How fast is the ball still traveling when it reaches net distance of 18m away?Assume the ball is still in motion on the ground the entire time.

A 1490 N crate is resting on a table connected to a 400 N block through a frictionless pulley system as shown.  Friction between the crate and the table is enough to keep the system at rest.  The arrows show the forces that act on the crate and the block.

A 0.280 kg potato is tied to a string with length 1.50 m, and the other end of the string is tied to a rigid support. The potato is held straight out horizontally from the point of support, with the string pulled taut, and is then released. Express your answer in meters per second.

pervious question: Same type of track as in the previous problem, this time with d = 4.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 7.57 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? New question:  OK, same sort of track, but now with d = 2.12 m. Now suppose the blocks starts on the track at x = 4.10 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case?     18.98 m/s     12.47 m/s     8.82 m/s     14.90 m/s

A horizontal spring with spring constant 290 N/m is compressed by 10 cm and then used to launch a 200 g box across the floor.
