**88. ssm The drawing shows two crates that are connected by a steel wire that passes over a pulley. The unstretched length of the wire is 1.5 m, and its cross-sectional area is 1.3 x 10-5 m². The pulley is frictionless and massless. When the crates are acceler- ating, determine the change in length of the wire. Ignore the mass of the wire. 3.0 kg 5.0 kg Problem 88

box with mass m goes down a ramp that makes an angle of 60 º with the horizontal. The ramp bands together to a flat section and then onto a circle track of radius R that ends where it's vertical. box is released from rest at a distance 3R above the horizontal and leaves the track at point A. all surfaces are frictionless. What force does the track exert on the box before it leaves the track?
1. A chain of length 0.7 m is at rest over two slopes, as shown in figure. First, assume there is no friction between the chain and the slope. If the chain is released from rest, which end of it will rise and what will its speed be when it reaches the top? Then assume that there is friction and calculate the minimum amount of friction necessary to prevent the chain from moving. 4 60° -0.3 m- xxxxx -0.4m- 30%
A 10 kg block rests on an inclined plane. The block is attached to a bucket by pulley system depicted below. The mass in the bucket is gradually increased by the addition of sand. At some point, the bucket will accumulate enough sand to set the block in motion. The coefficients of static and kinetic friction are 0.60 and 0.50 respectively. This is a 2 pulley system. The mass of the sand and bucket needed to start the block moving is 20.4 kg. Find the blocks acceleration, in [m/s2] up the plane?
